Regional variation in mutation rates R

Mutation rates vary at a fine scale - even within individual chromosomes. We are using statistical modeling to study such regional variation in mutation rates. Moreover, we are able to segment the genome into regions with high and low rates of different mutation types.

Mitochondrial mutation dynamics Mt

With sequencing now possible at high depth, we aim to examine mutation process directly, by examining the DNA of children and their parents. Mitochondrial DNA (mtDNA) provides a good starting point for such an investigation due to its compact size and high mutation rate.

Childhood obesity O

Obesity is becoming the major epidemic of the 21st century, and we are studying this disease in an integrated way - from the perspective of genomics, microbiomics, and epigenomics. We are following a large group of newborn children until they are at least 3 years of age.

Microsatellite variation and evolution Mc

We have investigated microsatellite evolution in the framework of a life-cycle hypothesis, according to which microsatellites are born and expand into adulthood, until their degradation and death. Microsatellites are implicated in numerous diseases and used as markers in population genetics and forensics.

Sex chromosome evolution S

We are determining the gene repertoire and structure of the Y chromosome in several mammalian species. The Y chromosome has very high rates of mutation compared with other chromosomes in the mammalian genome due to a higher number of cell divisions in the male than female germ line.

Postdoctoral position: Computational Biologist :
The Makova lab is looking to hire a computational postdoctoral researcher with knowledge of genomics for a project examining mitochondrial mutations and their transmission in humans from an evolutionary perspective (please see our recent publication in PNAS. Such knowledge is vital in a clinical setting when transmission risk for pathogenic mutations must be estimated. Our resources and links with medical researchers at Penn State College of Medicine and computational biologists from the Galaxy team put us in a great position to address these questions. A PhD in Computational Biology or related field is required. Candidates should be familiar with scientific programming and statistical analysis techniques. Experience with next-generation sequencing data analyses is desirable. You will be joining an established dynamic group. Penn State is a vibrant scientific community with particular strengths in computational genomics and molecular evolution. Our location, in State College, Pennsylvania, is known for excellent public schools, low cost of living, and numerous opportunities for outdoor activities. The starting date is flexible, with an earlier date preferred. Interested applicants should send a pdf with a CV, a statement of research interests, and contact information of three referees to Kateryna Makova at kdm16@psu.edu, indicating “mtDNA postdoc” in the subject line.
