Perelman School of Medicine at the University of Pennsylvania

Mathieson Lab

People

We have several fully-funded postdoctoral positions available. Please contact Iain if you are interested.

PhD students can join the lab through several programs, mainly Genetics and Epigenetics or Genomics and Computational Biology

Undergraduate students who are interested thesis projects (e.g. BIOL399) or paid research assistantships should send a CV and transcript to Iain, with a brief description of the areas you might be interested in.

Iain Mathieson

Iain Mathieson
Associate professor of genetics
 mathi@pennmedicine.upenn.edu

As well as the other projects in the lab, Iain is developing methods for inference of demography and selection from ancient DNA, and for the interpretation of genome-wide association studies


Alan Aw

Alan Aw
Postdoctoral Researcher

Trained in statistical genomics and applied mathematics, Alan is developing and applying methods to improve the generalizability of polygenic risk scores. He is also broadly interested in issues surrounding the use of genomic predictors in the era of personalized medicine.  


Laura Colbran

Laura Colbran
Postdoctoral Researcher
 Laura.Colbran@pennmedicine.upenn.edu

Laura is working to better understand the evolution of gene regulation and mechanisms of selection on complex traits, such as skin pigmentation.


Samantha L. Cox

Samantha L. Cox
Postdoctoral Researcher

Trained in physical anthropology, Sam is working to understand the evolution of anthropometric traits in humans, using morphological data, genome-wide association studies and ancient DNA. 


Dan Ju

Dan Ju
PhD Student
 danju@pennmedicine.upenn.edu

Co-advised by Sarah Tishkoff, Dan is using both ancient and modern DNA to understand the processes that drove the evolution of complex traits, including skin pigmentation and stature, throughout human history. 


Georgia Mies

Georgia Mies
PhD Student
 Georgia.Mies@Pennmedicine.upenn.edu

Georgia is studying how selection has shaped genetic landscapes and influenced susceptibility to diseases, focusing on cancer and immunity-related genes.


Fabian Ramos-Almodovar

Fabian Ramos-Almodovar
PhD Student
 Fabian.Ramos-Almodovar@Pennmedicine.upenn.edu

Fabian is working on methods for estimating the strength of stabilizing selection on complex traits, and on the evolution of mutation spectra across species. 


Kaeli Kaymak-Loveless

Kaeli Kaymak-Loveless
Undergraduate Researcher

Kaeli is working on genetic prediction of stature in ancient humans.
