Felix obtained his Ph.D. in Immunology from Cornell University working on retinoid biochemistry and metabolism. He has over 25 years research experience across a broad range of disciplines including biochemistry, molecular biology, developmental biology, systems biology, pharmaceutical science, environmental toxicology and endocrine disruption. His work helped establish a new mechanistic paradigm for obesity dependent on exposures to environmental toxic pollutants, e.g. organotins, and is credited with coining the term "obesogen." He has helped develop and expand on metabolomic capabilities at the facility.
 
Most recently he has served as the Academic & Outreach Coordinator for the Center for Complex Biological Systems where he contributed his expertise as an educator to implement a variety of educational initiatives and training activities, including national short courses.
 
Felix assumed the position of the MS Facility Director in October 2016. Please contact him for all questions regarding facility services, instrument open access training and project consultation.

Ben was recruited from Kansas State Univeristy and joined the MS Facility in July 2017 as our resident proteomics specialist.
 
He specializes in top-down protein analyses that place emphasis on determining the intact mass of proteins prior to enzymatic digestion. This powerful technique can be used in the discovery of new interacting proteomes, or to simply check recombinant protein preps in a high-throughput reproducible workflow. For the last 7 years at KSU he worked on numerous projects in the agricultural and forensics sectors helping bring quality control to a wide variety of protein products, and so is experienced in providing users high quality services and custom solutions to complex problems.
 
Ben provides core and advanced proteomics services, as well as supporting and training users on the Waters Xevo XS-QTOF, Synapt G2 Q-TOF and ABSciex MALDI 5800 instrument. If you have research needs for MALDI based protein identification, accurate peptide mapping, protein sequencing (gel bands or purified in solution) or protein modifications, please contact Ben for a consultation and assistance.
