My specific research interests lie at the interface of development, evolution, and ecology. I use comparative and experimental approaches to investigate the evolution of development (evo-devo) in growth chamber, greenhouse, and field studies.

Hobbies: 1) Gardening 2) Cooking international foods
Research blurb: I am currently investigating the genetic underpinnings of shifts in the threshold induction of a plastic phenotypic character (cleistogamous flowers) in Mimulus douglasii. Different populations of M. douglasii in California have drastically different population averages for the type of flower produced under controlled temperature and photoperiod conditions. Some populations have a low environmental response threshold for inducing cleistogamous flowers and some populations have a much higher threshold, which means they make more chasmogamous flowers than the other populations. The shift in threshold means differences in population inbreeding rate, resource use and duration of survival in the summer drought. Ultimately we would like to understand how and why the shifts in environmental response threshold have occurred.
Contributed Data: We have full genome (100bp paired-end, 40X coverage) sequence for Mimulus douglasii and Mimulus kelloggii. We also have lots of phenotypic data for M. douglasii. Additionally, we have a substantial amount of seeds for M. douglasii, M. kelloggii, and M. congdonii.

| Research interests: 1) Genetics of Adaptation 2) Phenotypic Plasticity 3) Evolution of Development 4) Domestication. Hobbies: 1) Baking 2) Biking. Research Blurb: My research program focuses on the genetics basis of adaptation and domestication, with a particular focus on traits related to developmental timing and its plasticity to daily and seasonal environmental cues. In particular, we seek to address three major questions: 1) how do organisms integrate environmental cues to trigger developmental events, 2) through what mechanisms does this plasticity evolve and 3) what natural or anthropogenic factors have driven or maintain this variation? One system where we have been pursuing these questions is through the genetics and ecology of natural variation in the photoperiod requirement for flowering among annual populations of Mimulus guttatus. Our work has demonstrated that longer days are required for flowering at higher elevations, and through quantitative genomic studies we have shown that the genetics of divergence in photoperiod threshold is simple within elevation transects but markedly polygenic across the species range. Current efforts are focused on working down to the nucleotide level and identifying the underlying genes through further genetic, gene expression, and functional studies. We are also expanding out to the ecological level by investigating the consequences of this allelic variation for flowering, fitness, and local adaptation in native habitats. Resources: Seed collections from many annual and some perennial M. guttatus populations along 10 altitudinal transects throughout California and Oregon

Research blurb: How do gene flow and local adaptation interact to define niche boundaries and geographic ranges? Answering this question is critical if we want to successfully manage ecosystems under climate change. I intend to use molecular tools, common-garden experiments, and experimental crosses to determine how gene flow between contrasting environments and hybridization influences current and future geographic distributions of Mimulus guttatus and Mimulus tilingii, monkeyflower species with contrasting altitudinal distributions.

|Research interests: 1) floral scent 2) reproductive isolation 3) pollination 4) phenotypic variation
Hobbies: 1) backpacking 2) cooking and baking
Research blurb: Research into pollinator-based prezygotic reproductive isolation in Mimulus is largely focused on floral color, which is controlled by a series of deposition and synthesis loci with differing alleles in each species. However, floral color is only one of many ways in which pollinators detect, evaluate, and interact with flowers. Based on prior research with hawkmoths and Mimulus (see below), Mimulus also uses floral scent to attract pollinators. My PhD work focused on identifying floral volatile differences in Mimulus lewisii and M. cardinalis and determining which were important for bumblebee pollinators. Three volatiles were identified as critical for bumblebee attraction to M. lewisii; we identified their genetic basis, created knockdown transgenics in M. lewisii, and tested them in the greenhouse with free-flying captive bumblebees. We found that knockdown of one gene (and one volatile product) produced a significant decrease in bumblebee visitation. Separately, I am investigating floral scent across section Erythranthe, and collecting published and anecdotal data on pollinator identities in the entirety of Mimulus.

Research blurb: The niche breadth hypothesis looks to variation in environmental tolerances to explain differences in species’ geographic ranges. I am investigating range-wide trait variation in monkeyflowers to determine if species with high phenotypic variation occur across a greater suite of environments and how trait data adds to our understanding of niche breadth. This phenotypic variation can be produced through plasticity or local adaptation, and a central goal of my thesis is to experimentally test how these two mechanisms contribute to niche breadth. I am using a multi-population approach to determine how the predominant mechanism will vary across the landscape and to see how niche breadth is partitioned within or between populations. Finally, as my first step towards understanding how mating system variation fits into this mosaic, I am investigating population-level variation in autonomous selfing ability and floral traits along an elevation gradient.

Hobbies: 1) salsa dancing 2) now that I have a new baby – sleeping
Research blurb: Evolution sometimes yields independent yet similar-looking traits. Discovering the genetic changes and molecular mechanisms underlying repeated (parallel or convergent) phenotypic evolution can show how, and to what extent, evolution is genetically constrained and thus predictable. I am interested in the parallel evolution of floral color patterning in a colorful group of monkeyflowers from Chile. The monophyletic luteus group belongs to the Simiolus section, which displays highly conserved floral pigmentation: yellow carotenoids in the petals, and small dots of red anthocyanins in the throat area. The luteus group is a splashy exception, containing purple-, orange-, and pink-flowered species. All three of these derived phenotypes are caused by an expansion of anthocyanins in the petal area, and all three expansions appear to have occurred independently – but how, and why? In addition to genetic mapping and molecular characterization of the causal genes and mutations, I am exploring fitness consequences of these dramatic and recent evolutionary changes..

Hobbies: 1) Cooking/Baking 2) eating what I’ve cooked or baked 3) running 4) reading Jane Austen 5) aesthetics
Research blurb: I am broadly interested in the genetics of adaptation and speciation. I am particularly interested in how organisms adapt to different local environments. In my post-doc work I am examining phenotypic variation in the house mouse, Mus domesticus, along a latitudinal cline from Brazil to upstate New York. House mice have recently colonized and expanded across the Americas from Europe. I am particularly interested in potential differences in metabolic and life history traits between populations at the extremes of this cline.
In my PhD work I studied the genetics of adaptation to granite outcrop environments in the Mimulus guttatus species complex. M. laciniatus is a member of this closely related group of monkey flowers that is endemic to the Californian Sierra Nevada mountain range. This species occurs in the middle of dry, exposed granite outcrops from mid to high elevation. Just meters away the ancestral M. guttatus grows in adjacent seeps and streams. How has M. laciniatus adapted to its comparatively harsh local environment? To answer this question I investigated the genetic architecture and adaptive significance of differences in flowering time, mating system, and leaf shape between M. laciniatus and M. guttatus using combination of QTL mapping with next gen sequencing and reciprocal transplants with hybrid individuals in the field.

|Research interests: 1) Local adaptation 2) Speciation 3) Quantitative genetics 4) Landscape evolutionary genomics. Hobbies: 1) Parenting 2) Being outside. Research blurb: My research program is centered on identifying the genetic and genomic mechanisms of ecological adaptations and how those adaptations contribute to the formation of new species. A primary focus of my research is to understand how differences in water availability between habitats drives adaptation in plant species. To this end, I am studying the genetic basis of adaptive divergence and reproductive isolation between coastal perennial and inland annual ecotypes of the yellow monkeyflower (Mimulus guttatus). During graduate school, I discovered a chromosomal inversion that differentiates the annual and perennial ecotypes across western North America. The inversion polymorphism contributes to a suite of adaptive phenotypic traits including the perennial/annual life-history transition. Using field experiments, I demonstrated that the inversion contributes to ecological adaptation and multiple reproductive isolating barriers between ecotypes. I am now focused on determining the genetic and physiological mechanisms by which the inversion contributes phenotypic divergence between annuals and perennial populations.|

My lab studies plant diversity and evolution, with a particular emphasis on the diversification of reproductive strategies and speciation. Our overarching goal is to understand how ecological, genetic and evolutionary processes interact to generate the amazing diversity of flowering plants. To tackle this main goal, we use a combination of field and glasshouse experiments, genetic and genomic analyses, phylogenetics, and theoretical models.For the past 5 years we have been studying introduced populations of Mimulus spp. in the United Kingdom and beyond. We recently discovered the most recently speciation event in Mimulus, the allopolyploid M. peregrinus, which has started a new collaborative research program in my lab on the ecological genomics of polyploid speciation and rapid evolution.Please get in touch with me if you are interested in a PhD or postdoctoral position in my Lab.

|Research interests: 1) adaptation 2) ecophysiology 3) speciation 4) genetics of adaptation
Hobbies: 1) distance running 2) backpacking Research blurb: I am an evolutionary biologist who uses ecophysiology as a way to connect fitness tradeoffs to local adaptation and speciation. Physiologists have discovered numerous tradeoffs that organisms must confront in order to survive and reproduce in a given environment. Such fitness tradeoffs are the theoretical foundation for most evolutionary models of local adaptation and speciation. Despite decades of interest in an evolutionary physiology synthesis, there is still little integration between fields. The result is that we know little about the role of physiological tradeoffs in adaptive evolution, even though such tradeoffs are widely assumed to be a significant cause of divergent natural selection between populations. The goal of my research is to renew and advance an evolutionary physiology synthesis in plants using comparative methods, genetics, field studies, and theory.

|Research interests and blurb: I’ve been involved in taxonomy pretty much straight through since school, primarily as a student of Asteraceae until 2009, when I was employed by FNA to provide treatments of miscellaneous families and genera. In all, I’ve published studies including more than 25 plant families –– see website list of all pubs –– mostly in North America, sporadically ranging further outward. Primarily circumscriptions of species and, when appropriate (as in Mimulus and others), definitions of genera.

Hobbies: 1)Travel 2)Watch TV series and movies
Research blurb: I am working with invasive Mimulus guttatus in United Kingdom. As many plants has the capacity of reproducing by sexual and asexual means simultaneously it is expected to be a trade-off between sexual and asexual reproduction. even if the trade-off has a genetic basis the expression of trade-offs can vary among environments. For instance, a phenotypic trade-off can be obscured under very good resource availability, but revealed under resource poor conditions. Therefore phenotypic correlation between traits may be determined by a combination of genetic and environment.
Previous studies with Mimulus guttatus have shown that the allocation between sexual and asexual reproduction varies with latitude both in native and introduced range, however it is not known what environmental factors may affect the expression of trade-off between both modes of reproduction. The objective of this experiment is to determine if is there a phenotypic trade-off between production of flowers and vegetative reproduction (clonal reproduction), if is there a clinal variation in this trade-off and to what extent such a trade-off is affected by environmental characteristics such as nutrient and space availability. I am developing common garden experiment with 13 populations from different latitudes in UK to address these questions.

Research blurb: Fred Ganders first alerted to the prospects of Mimulus when I did a post-doc with him at UBC Botany. In my first position at U. Toronto Botany, I would relish the Spring visit to California. Toronto would be leafless and lifeless and California a bouquet of flowers. In Toronto I did entirely Mimulus work (with theory added). Next I went to UBC where I (actually my students and post-docs) did research with many organisms, including the “Spirit Bear”. I had 3 people work on Mimulus since 1996. In 2001 we got the very first Genome Canada grant. We have had Forestry (tree) genome grants continuously since then. For my next NSERC grant (equivalent to NSF kind of), I intend to use next-gen sequencing for expression QTL mapping and gene expression evolution in Mimulus.

Research blurb: Research in my lab lies at the interface among ecology, evolution, genetics, and genomics. The major objective of this research program is to dissect the processes of adaptive evolution and speciation in natural plant populations. To do so involves a thorough examination of the mechanisms that link genotype, phenotype, and fitness in nature. Therefore, it is necessary to (i) quantify the strength, patterns, and agents of natural selection affecting ecologically important traits, (ii) characterize the molecular basis for this phenotypic change, (iii) assess whether molecular signatures of selection exist in these genomic regions, and (iv) re-create the historical events that led to the origin and spread of adaptive alleles. We examine geographic variation among members of the diverse Mimulus aurantiacus (sticky monkeyflower) complex.

Research blurb: I am broadly interested in how plants respond to their local environments, and the role those adaptations play in diversification at the genomic, population, and species levels. While evidence for local adaptation in plants is abundant, much less is known about the particular traits and genes that confer this specialization to specific environments. My research uses the wildflower genera Ipomopsis and Mimulus (mostly M. guttatus and M. tilingii) to examine how environmental heterogeneity influences phenotypic and genetic variation among natural plant populations. I combine observations of natural populations and experimental manipulations in the field and greenhouse with tools from quantitative genetics and physiological ecology. Together, these studies provide insight into how environmental stresses, adaptation to these conditions, and evolutionary change are intertwined, using tractable, ecologically relevant systems.

Hobbies: 1) Table tennis 2) Fishing
Research blurb: Currently we focus on two major lines of research: (1) Developmental genetics of ecologically important floral traits, including carotenoid pigmentation, corolla tube formation and elaboration, stamen and pistil arrangement, nectar volume, etc. Very little is known about the genes and developmental networks regulating these floral traits, largely because the conventional genetic model system, Arabidopsis, is not particularly suitable to study them. Our work leverages the recently developed genomic resources, stable transgenic tools, and chemically induced mutants of Mimulus lewisii to address this problem. In addition, we are carrying out a large scale transposon-mediated activation tagging experiment in M. lewisii to generate gain-of-function mutants, to complement what we could learn from chemically induced, loss-of-function mutants. (2) The genetic bases and developmental mechanisms underlying the tremendous variation of flower color patterns and corolla tube shapes among natural Mimulus species. At the moment we are mainly working on anthocyanin pigmentation patterns, but we will certainly get into carotenoid pigmentation and corolla tube variation once we have learned more about the basic developmental genetics of these traits from the M. lewisii mutants.
