Our lab studies the biological basis for individual variation. The genetic architecture of complex traits is not a static blueprint of the phenotype; rather, it is highly dynamic and context-dependent. In many ways, we study the ecology of the genome: how do genes interact with each other and their environment to shape variation between individuals? We address this question using a combination of approaches focused on studying natural genetic variation from the lab to the field and from Drosophila to humans.
We are always looking for curious and motivated graduate students and have various opportunities for postdocs. If you’re interested, please don’t hesitate to contact us.



Do modern diseases arise from genomes living in the past?


In a blink of evolutionary time, humans have explored every corner of this planet and have shown an amazing capacity to adapt to extreme conditions. The Turkana, a seminomadic pastoralist tribe, live in northern Kenya in one of the most arid environments in the world. Having retained their traditional lifestyle, the Turkana provide a rare opportunity to address how ecological pressures and natural selection shape human genetic variation (a question we will explore using whole genome sequencing). Further, because of recent infrastructure developments, many Turkana are moving away from their ancestral lands and into cities. This unique situation allows us to ask another important question: what happens when a locally adapted population is transplanted to a novel urban environment? Such urban-rural migrations are commonly accompanied by an increased risk of chronic diseases; yet, our mechanistic understanding of how these transitions impact health is limited.  To address this gap, we are contrasting  transcriptomic and phenotypic data collected from traditional Turkana versus those that have moved, within their lifetime, to major cities. Together, this work not only allow us to retrace human evolutionary history, but to understand how the disruption of locally adapted systems may lead to disease.


About the Turkana people

The Turkana people inhabit one of the most arid ecosystems in East Africa, with year-round highs of 100F and low levels of seasonal, unpredictable rainfall. The Turkana are pastoral nomads, and 80% of their diet is derived from milk or other animal products. Daily protein intake is thus extremely high (300% of the WHO requirements), but total caloric intake is low (1,300-1,600 kcal/day for adults). Turkana are consequently very lean, yet they undertake the arduous task of collecting water on a daily basis. This process typically involves walking several kilometers (5 to 10 km is not unusual) to wells dug in dry river beds, and hauling water up from the bottom of a well (which can exceed 30 feet during the dry season). Water must then be carried back to the home and shared among family and livestock. As a result, the Turkana drink relatively little water on a daily basis, while tolerating extreme heat and exerting considerable energy; they do so despite limited caloric reserves and a protein-rich diet, which takes considerably more energy to digest than fats or carbohydrates. This extreme lifestyle has likely selected for numerous physiological adaptations in the Turkana people that we aim to uncover.



We are very fortunate to work with amazing team based at the Mpala Research Center under the directorship of our collaborator Dr Dino Martins.


Why do some individuals appear to be more sensitive than others to environmental perturbation?


The answer to this question has broad implications ranging from our ability to make predictions about disease risk from genotype, to our ability to identify the drivers of inter-individual variability, and our understanding of toxicity mode-of-action.  Exploring the contribution of genotype-by-environment interactions (GxE) to individual variation has been very challenging in humans, where epidemiological studies exploring GxE are generally underpowered, have difficulties quantifying environmental exposure. To address this problem we created a new community resource to study the genetic basis of complex trait variation in Drosophila melanogaster composed of large, synthetic outbred populations. The approach we outline enables us to break  away from traditional, and often underpowered approaches that have relied on inbred strains or RILs. With this new and versatile community resource, we can rear thousands of genetically unique flies drawn from a common genetic pool, expose them to a range of different environments and contrast the ensuing genetic architectures

Data we have collected over the past couple of years indicate that differences in individual sensitivity emerge from the disruption of regulatory systems where individuals that are more sensitive to environmental stress have decreased transcriptional robustness for many genes and that this variation in robustness is under genetic control. We have developed an analytical framework to identify context-dependent transcriptional networks and the polymorphisms that control this variation. The impact of mutations that affect environmental sensitivity are heavily dependent on the interaction between genetic background and environmental stress simultaneously. As important as they are, the epistatic interactions associated with variation in penetrance have been notoriously difficult to identify. We are currently developing experiment and statistical approaches aimed at mapping and testing the contribution of such interaction of individual variation in environmental sensitivity.


Can the microbiome influence host evolutionary trajectories?


The microbiome shapes many traits in hosts, but we still do not understand how it influences host evolution. To impact host evolution, the microbiome must be heritable and have phenotypic effects on the host. However, the complex inheritance and context-dependence of the microbiome challenges traditional models of organismal evolution.  We take a multifaceted approach to identify conditions in which the microbiome influences host evolutionary trajectories.

We are currently exploring quantitative genetic models to study how microbial inheritance and phenotypic effects can modulate host evolutionary responses to selection. We are particularly interested in how hosts may leverage locally adapted microbes, increasing survivorship in stressful environments. As well as how microbial variation may increase host phenotypic variation, enabling exploration of novel fitness landscapes.

The complex interplay between host and microbial genetic variation is surprisingly understudied. We use a combination of approaches from experimental evolution in Drosophila to ecological sampling in humans across environmental gradients and lifestyle. We aim to incorporating microbial variation in standard evolutionary and quantitative genetics model to better understand how phenotypic variation is generated, and subsequently, how selection operates across ecological and evolutionary scales.


It is well established in quantitative genetics that stressful environmental exposure tends to increase the phenotypic variance of a population, but how and why?

This is a fundamental question for any biologist interested in understanding the genetic basis of variation for complex traits.  Although studies of development, morphology and animal breeding have long noted the heterogeneity of variance among genotypes, this axis of variation has received little attention compared to the effect of genetic variation on trait means. There is now clear evidence for the importance of genetic control of variance and that variance itself is a quantitative trait. This has important implications both in medical genetics and evolutionary biology. If different genetic? backgrounds differ in their? propensity for phenotypic variability, then individuals derived from a high-variability genetic background may exhibit an extreme phenotype by chance alone. A property of that genotype that would not have been informed by traditional mean focused quantitative genetic approaches. In the context of evolutionary change, this could accelerate or slow down adaptation to new conditions. With respect to health, this could result in disease, changes in variance can affect the probability of individuals finding itself in the tails of the distribution. Therefore, by focusing primarily on the effect of genetic variation on trait averages and ignoring its effect on variance, we may be missing a very important axis contributing to phenotypic variation.
Our lab explores this problem both from an evolutionary perspective asking: under what scenario might variance control evolve? What evolutionary forces maintain variation for alleles controlling phenotypic variability?  And from a medical perspective: how does variance control affect our ability to make predictions from genotype to phenotype? Does the presence of variance increasing alleles increase the probability an individual being in the tail of distribution?

A major focus of the lab is to study how genotype-by-genotype and genotype-by-environment interaction modulates gene regulatory networks and ultimately shape individual variation.
The current quantitative genetic paradigm is driven by a prevailing view that additive genetic models – focused on the mean effect of alternative alleles – adequately explain variation for most phenotypes. Unfortunately, a decade after the popularization of GWAS and in spite of much effort, we have fallen short of the goal of explaining most of the heritability for complex traits in terms of allelic effects. This averaging approach is designed to describe the mean effect of an allele randomized over a large number of the genetic backgrounds and environments. But each individual has faced a unique trajectory of environmental insults, some of which may have quite large genotype-specific effects.
A fast-growing body of evidence indicates that the genotype-phenotype map is much more complicated than Fisher’s additive model would predict. When measurements can be made with reasonable control of the environment, complex, non-additive interrelationships between loci appear to be the rule and not the exception. Furthermore, these allelic effects are often environmentally sensitive. The paradigm derived from traditional quantitative genetics is at odds with a major goal of genetics as we often seek to understand the causal path from genotype to phenotype for individuals and not populations.
sys gen1In Drosophila, we have developed a unique resource for mapping variation in complex traits using large synthetic Drosophila outbred populations. These genetically diverse mapping panels allow us to control genetic background and allele frequency as well as the environment of each population. Notably, our method breaks away from traditional approaches that often rely on problematic inbred strains. This allows us to rear thousands of genetically unique flies, drawn from a common genetic pool, expose them to different environments and study the combined effect of genetic background and environment perturbation. We are currently focusing on metabolic traits.
sys gen2

In humans, we are collaborating with the lab of Dr Paivi Pajukanta at UCLA and are taking a systems genetics approach to the study of metabolic syndromes (METSIN cohort). Our laboratory has developed fully automated approaches to perform transcriptional profiling at high-throughput for a fraction of the cost of currently available methods. This is allowing us to profile a large number of individuals and use a systems genetics approach to study metabolic variation, echoing our work in flies.

Understanding the genetic basis of complex traits demands that we go beyond describing the relationships between polymorphic DNA and phenotypic variation. To that end we take a system genetics approach, simultaneously measuring variation at multiple levels of biological organization is a necessary first step. Patterns of transcriptional correlation allow the construction of co-expression networks describing how genetic variation affects transcriptional variation (i.e. eQTL), and how directed transcriptional networks in turn correlate with phenotypic variation. Together, this information will allow us to draw the causal path from variation in allele frequency to a phenotypic differences between individuals. Such directionality indicates the flow of biological information and sets the framework through which perturbations can be predicted. This is the promise of systems genetics – the formulation of causal predictions painting a detailed picture of a dynamic genotype-phenotype map.

TM3’seq: a tagmentation-mediated 3’ sequencing approach for improving scalability of RNA-seq experiments


RNA-seq has become the standard tool for collecting genome-wide expression data in very diverse fields, from ecology and developmental biology to quantitative genetics and medical genomics. However, RNA-seq library preparation as well as its sequencing requirements are still prohibitive for many laboratories, in particular when large sample sizes are involved. Recently, the field of single-cell transcriptomics has been able to reduce costs and increase throughput by adopting an approach that barcodes individual samples during reverse transcription and pools them before cDNA synthesis, effectively processing a single sample for most of the library preparation procedure. In contrast, RNA-seq protocols where each sample is processed individually are significantly more expensive and lower throughput than single-cell approaches. Yet, many experimental approaches are designed around follow-up experiments on a subset of samples, and therefore require that individual libraries are generated for each sample. In order to fill this gap, we have developed TM3’seq, a 3’-enriched library preparation protocol that uses Tn5 transposase and preserves the sample identity at each step. TM3’seq is designed for the high-throughput processing of individual samples (96 samples in 6h, with only 3h hands-on time) at a fraction of the cost of commercial kits ($1.5 per sample), while recovering gene expression profiles of the same quality as the commercial kits. We expect that the cost- and time-efficient features of TM3’seq make large-scale RNA-seq experiments more permissive for the entire scientific community.
