Current Lab Members

Greg Lang

Assistant Professor

I received my Ph.D. in Molecular Biology with Andrew Murray at Harvard where I studied mutation rate variation in yeast. I then worked as a post doc in David Botstein's lab at Princeton. There I developed, in collaboration with Michael Desai, a system for high-throughput experimental evolution in yeast. I joined the faculty at Lehigh in 2013. Starting in 2018 I will be an instructor for the CSHL Yeast Genetics & Genomics course. I'm told I need to smile more in photos.

Dimitra Aggeli


During my Ph.D. I studied aspects of the regulation of the actin cytoskeleton in S. cerevisiae in the laboratory of David Amberg at SUNY Upstate Medical University. Before joining the lab, I was a postdoc at Stanford University, where I developed a sequencing-based method for the detection of single nucleotide polymorphisms, under the supervision of Gavin Sherlock and William Greenleaf. I am interested in the allelic interactions during diploid evolution, and the consequences of historical contingency during adaptation.

Dan Marad

Graduate Student, Molecular Biology

I received my Bachelor's degree in Molecular and Cell Biology from Ursinus College in 2014. While there, I studied yeast prion formation and propagation. I'm studying the impact of ploidy on laboratory yeast evolution.

Ryan Vignogna

Graduate Student, Biochemistry

Before joining the Lang lab in 2016, I received my undergraduate degree in Biochemistry and Molecular Biology from DeSales University. I am interested in tackling a central question of evolutionary biology: how reproducible is evolution? My specific interest, and current project, lies in understanding how epistasis shapes evolutionary paths and outcomes.

Andrew Conboy

Graduate Student, Evolutionary Biology

Before joining the lab, I received my Bachelor's degree in Environmental Science at Chestnut Hill College in 2018. While there, I studied watershed ecosystems and was involved with the SEA-PHAGES program. In the Lang Lab, I am currently learning to use long-read sequencing to better resolve large structural mutations in evolved populations.

Artemiza Martinez

Rotation Student, Molecular Biology

I received my Bachelor’s in Biotechnology Engineer from The Autonomous University of Queretaro, Mexico. I conducted my undergraduate dissertation thesis at the International Laboratory for Human Genome Research (LIIGH), which consisted of editing Saccharomycotina yeast genomes utilizing CRISPR-Cas9 for artificially construction of interspecies hybrids. I am passionate about rock climbing; the farther my feet are from the ground the better.

Ginger Gerhold


I am currently pursuing a Bachelor of Science in Business and Economics as a Marketing major. Additionally, I am taking pre-dental coursework in hopes of going to dental school. Before graduation, I wanted the opportunity to have a more hands-on experience in the sciences and my interest in microbiology led me to Lang Lab, where I am currently studying different mating types of yeast. Outside of the lab, I enjoy rewatching episodes of Grey’s Anatomy and finding new recipes to try out!

Bryan Novak


I am currently in the College of Arts and Sciences at Lehigh University, pursuing a Bachelor's degree in Behavioral Neuroscience with a minor in Business. While at Lehigh, I became interested in the Lang Lab after learning about some of the research completed through a work-study. I am eager to partake in various projects and understand more about the wonderful modern organism, yeast. I enjoy eating chipotle, always.

Opportunities for Students and Postdocs

We are always looking for talented students and postdocs who are interested in experimental evolution to join the lab. Molecular evolution is by nature interdisciplinary; therefore students from a variety of backgrounds (e.g. evolutionary biology, molecular biology, physics, math, chemistry, computer science, engineering, and systems biology) are all encouraged to apply.
Graduate Students: Graduate students enter the lab through the Graduate Program in the Department of Biological Sciences. We have three PhD programs: Molecular Biology, Integrative Biology (which includes evolutionary biology), and Biochemistry.
Post Docs: If you are interested in joining the lab, please send an email to describing your research background, along with a current cv, and contact information for three references.
Undergraduate Students: Undergraduates are welcome in the lab. If you are interested please see our work study ad or send an email to
