Current Lab Members

Greg Lang

Associate Professor

I was a Ph.D. student with Andrew Murray at Harvard and a post doc with David Botstein at Princeton. I joined the faculty at Lehigh in 2013. My interests comfortably span evolutionary and molecular biology. My lab works mostly on yeast genetics and genomics. I am an instructor for the CSHL Yeast Genetics & Genomics course.

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.

Han-Ying Jhuang


I’m generally interested in evolutionary biology and biotechnology. During my Ph.D. with Dr. Jun-Yi Leu at Academia Sinica, I studied hybrid nuclear-mitochondrial incompatibilities in yeast. As a postdoc in Dr. Michael Springer’s lab at Harvard, I developed a system for analyzing complex traits from large-scale variant pools. In addition, I studied how the sugar ratio-sensing behavior in yeast is affected by the environment, and I used barcoded yeast to track objects provenance. At Lehigh, I’m enthusiastic in how pathways evolve in related species.

Artemiza Martinez

Graduate 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.

Dominick Costanzo

Rotation Student, Biology

Brooke Dubyna

Rotation Student, Biology

Grace Allen


I am currently in the College of Arts and Sciences at Lehigh University, pursuing a Bachelor's degree in Biology with a minor in Psychology. Post Lehigh I have the hopes of attending Physicians Assistant school. I became a part of the Lang Lab as microbiology is a growing interest of mine. I am excited to gain more hands-on experience in a research lab and intend to further study the mating pathway of yeast. Outside of the lab, I love spending time with my labradoodle Hurley.

Will Yaeger


I am pursuing an interdisciplinary B.S. in Biology, Systems Engineering, and Sustainable Development through Lehigh’s IDEAS honors program. I am interested in microbial ecology and genetics and particularly fascinated by fungi. My current work in the lab is focused on hybridization in Saccharomyces species. Upon graduation, I intend to pursue a career in applied microbial research and work to develop biological solutions to climate- and agriculture-related issues. Outside of classes and research, I enjoy reading and spending time outdoors hunting mushrooms or backpacking with friends.

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.
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
