BACKGROUND
In 1999, Michelle Puchowicz received her Ph.D. in Nutrition from Case Western Reserve University (CASE), following her undergraduate studies in Biomedical Engineering (CASE).  As a graduate student Dr. Puchowicz studied the applications of Nutrition and Metabolism using in vivo animal models and stable isotopes & mass isotopomer analysis to characterize whole body metabolism of short-chain synthetic nutrients.

During her Post-doctoral / Research Associate work at CASE, she specialized in the effects hypoxia, ischemia, and ketosis on energy metabolism in brain. Dr. Puchowicz focused on developing treatments for ischemic reperfusion injury and mathematical modeling of brain metabolism. She was the first to show that diet-induced ketosis can protect against stroke-induced brain injury.  She also discovered that ketosis increases capillary density in the brain, a mechanism that may underlie its neuroprotective effect.

As a faculty member in the Department of Nutrition at CASE, Dr. Puchowicz continues to study energy metabolism in whole body and brain. She is experienced in using in vivo animal models and stable isotopomer analysis to study intermediary metabolism. The use of rodent models, synthetic nutrients / related nutritional compounds and mass spectrometry technologies enables her to study and develop potential treatment strategies for the management of pathologies/diseases associated with metabolic defects in energetics and metabolism.

As the Director of the Metabolomic and Analytical Core of the Case MMPC (Metabolic Phenotyping Center), Dr. Puchowicz spends a substantial amount of time consulting with investigators (local, outside the University, and abroad).  As such, she discusses ways to design their experiments, perform procedures and complete analyses.  Fitting with the overall mission of the National MMPC Consortium, Michelle Puchowicz is committed to helping the research community at-large by providing precise metabolic and physiologic phenotyping services for mouse and rat models of diabetes, diabetic complications, obesity and others associated metabolic disorders.

RESEARCH INTERESTS

Metabolomics; brain and body energy metabolism; regulation of fatty acid, ketone body and glucose metabolism; mass spectrometry.


TEACHING
Dr. Puchowicz mentors undergraduate and graduate students with various science / engineering backgrounds on their research projects. This is achieved through individual mentoring and course work.   Michelle Puchowicz is also a regular faculty member for the week-long MMPC Consortium course "Isotope Tracers in Metabolic Research: Principles and Practice of Kinetic Analysis" held once a year in Little Rock, Arkansas.
