gene regulation in mouse macrophages

gene icon We use a computational systems biology approach to study gene regulation in health and disease. We integrate cellular and molecular information on a variety of scales within network models that we analyze in order to uncover molecular mechanisms. Our long-term goal is to use the tools of computational systems biology to advance precision medicine. We use cross-species approaches in our work, integrating canine and human datasets in the case of cancer and human and mouse datasets in the case of cardiovascular disease. Our research has been supported by funding from the National Institutes of Health, the National Science Foundation (via a 2016 Career award), the Medical Research Foundation of Oregon, the PhRMA Foundation, and the Animal Cancer Foundation.

   [link to studio portrait]
Stephen earned a PhD in physics from the University of Maryland and an ScB in mathematical physics from Brown University. Building on his computational modeling background from physics, Stephen joined the University of Washington Genome Center as a senior fellow, where he worked on genome mapping algorithms in Maynard Olson's laboratory. Stephen's work on the Human Genome Project paved the way toward more molecular- and network-oriented research projects – primarily in the area of gene regulatory network modeling, analysis, and inference – in the labs of Hamid Bolouri and Ilya Shmulevich at the Institute for Systems Biology. Prior to joining OSU, Stephen held a senior scientist appointment in Alan Aderem's laboratory at the Center for Infectious Disease Research, where his work on computational methods for mapping gene networks earned him a K25 Career Development Award from the National Institutes of Health. At OSU, Stephen holds a dual appointment in the Department of Biomedical Sciences and in the School of Electrical Engineering and Computer Science. Stephen received an NSF CAREER award in 2016.

Graduate programs that I work with

I can mentor graduate students in any of four graduate programs: Computer Science, Electrical and Computer Engineering, Molecular and Cellular Biology, or Comparative Health Sciences. I thoroughly vet applicantions for positions in my lab through a process that includes review of prior research accomplishments, prior academic work, faculty reference letters, writing samples, test scores, evidence of professionalism, and evidence of computational and mathematical proficiency.

Compbio @ OSU

Our lab bridges the Department of Biomedical Sciences and the School of Electrical Engineering and Computer Science, and we interact with students and researchers from diverse areas of the life sciences and from computer science, statistics, and engineering. The academic environment for interdisciplinary collaborations in computational biology at OSU is outstanding, with the Center for Genome Research and Biocomputing (CGRB) serving as a hub for computational infrastructure, training, collaboration, and genomics core facilities. Computational biology researchers at OSU interact frequently to share ideas, though CGRB-sponsored seminars, bioinformatics user group meetings, training sessions, and twice-yearly computational biology / genomics workshops. Biocomputing is a rapid growth area for OSU, with four faculty hired in this area during 2013 and additional biocomputing hires planned in the near future. Your research will be powered by the bioinformatics computing cluster in the Center for Genome Research and Biocomputing (CGRB) and the 16 TFLOPS high-performance computing system in the College of Engineering.

About Corvallis

OSU is in Corvallis, an intellectually rich and bike-friendly university town in the beautiful Willamette Valley of Oregon. Corvallis is renowned for outdoor recreation and for quality-of-life. In addition to the thriving social and intellectual environment in Corvallis, the city of Eugene (which hosts the University of Oregon) is only 50 minutes away, and Portland (which hosts Reed College, Oregon Health and Sciences University, and Portland State University) is only 90 minutes away. Charming coastal communities like Newport (where the Hatfield Marine Science Center is located), are only an hour away. For more information about Oregon State University, see the OSU website.

We value diversity

Oregon State University is an Equal Opportunity Employer and the Ramsey Lab group members respect and value diversity in the workplace.
