Sharon Majchrzak-HongResearch Chemist

Sharon has over 10 years of experience in the field of lipid research; including chemical and data analysis from both animal laboratory experiments and human clinical studies.  She received her BS in Biochemistry and her BA in Chemistry from the University of Rochester (Rochester, NY) in 1994 and her MS in Natural Sciences from the University of Buffalo Roswell Park Graduate Division in 2003.   Her laboratory work at the LMBB/SNN has included fatty acid chemical analysis using the techniques of gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS), solid phase extraction (SPE), high pressure liquid chromatography (HPLC) and liquid-liquid extraction.   She has also been involved in artificial rearing (AR) nutritional studies for infant rodent models. 

Her current projects for the LMBB/SNN include providing lab and data management support for our ongoing clinical protocols.  One of the trials she is working on is the NIAAA-led multi-institute collaborative randomized controlled trial titled Dietary linoleic acid regulation of omega-3 HUFA metabolism; satiety and body composition among overweight female subjects.  In this dietary study we are investigating the effects of controlled alterations in dietary omega-6 (n-6) linoleic acid (precursor to n-6 endocannabinoids) and n-3 fatty acids (precursors to n-3 endocannabinoids) on craving, satiety, behavior and body composition.  The other clinical trial she is providing support on is the Neuroimaging Omega-3 and Reward in adults with ADHD (NORAA) trial.  In the NORAA trial we are investigating the effects of omega-3 supplementation on brain reward function in adults with ADHD as well as behavioral and biochemical endpoints.

Her research interests include lipid biochemistry, nutrition and neuroscience.  She may be contacted at 301-435-4029 or
