Thomas Jaramillo
Associate Professor of Chemical Engineering, of Photon Science and Senior Fellow at the Precourt Institute for Energy
BioRecent years have seen unprecedented motivation for the emergence of new energy technologies. Global dependence on fossil fuels, however, will persist until alternate technologies can compete economically. We must develop means to produce energy (or energy carriers) from renewable sources and then convert them to work as efficiently and cleanly as possible. Catalysis is energy conversion, and the Jaramillo laboratory focuses on fundamental catalytic processes occurring on solid-state surfaces in both the production and consumption of energy. Chemical-to-electrical and electrical-to-chemical energy conversion are at the core of the research. Nanoparticles, metals, alloys, sulfides, nitrides, carbides, phosphides, oxides, and biomimetic organo-metallic complexes comprise the toolkit of materials that can help change the energy landscape. Tailoring catalyst surfaces to fit the chemistry is our primary challenge.

Razieh Khalifehzadeh
Postdoctoral Scholar, Chemical Engineering
BioDr. Khalifehzadeh received a dual Ph.D. in Chemical Engineering and Nanotechnology & Molecular Engineering from the University of Washington (UW) in 2018. During her graduate studies in Prof. Buddy Ratner’s laboratory, she obtained fundamental training in biomaterials design, polymer chemistry, tissue-implant interactions and learned about FDA regulations and clinical translation process of medical devices. Her research was focused on development of new classes of degradable polymers for cardiovascular stents. Throughout her graduate study, she received multiple prestigious awards such as Pre-doctoral Clinical Research Training (TL1) scholarship from National Center for Advancing Translational Science at NIH, Society for Biomaterials (SFB) travel award, Dean of Engineering Scholarship and Graduate School Fund for Excellence and Innovation. She is currently a NIH K99/R00 postdoctoral fellow in Prof. Zhenan Bao’s laboratory at Stanford and her research is focused on designing bioelectronic platforms for early diagnosis of cancers, with emphasis on brain tumors. Her interdisciplinary research lies at the interface of engineering and translational medicine and focuses on the development of polymer-based, wireless, implantable or wearable bioelectronics for disease diagnosis and therapy. She is a member of Diversity Initiative center at Stanford and has been consistently involved in leading efforts to promote diversity among underrepresented and socioeconomically disadvantaged students. She serves on various diversity committees and plans to continue her efforts by creating and leading outreach programs as a future independent investigator.

Wells H. Rauser and Harold M. Petiprin Professor and Professor of Chemistry and, by courtesy, of Biochemistry
Current Research and Scholarly InterestsResearch in this laboratory focuses on problems where deep insights into enzymology and metabolism can be harnessed to improve human health.
For the past two decades, we have studied and engineered enzymatic assembly lines called polyketide synthases that catalyze the biosynthesis of structurally complex and medicinally fascinating antibiotics in bacteria. An example of such an assembly line is found in the erythromycin biosynthetic pathway. Our current focus is on understanding the structure and mechanism of this polyketide synthase. At the same time, we are developing methods to decode the vast and growing number of orphan polyketide assembly lines in the sequence databases.
For more than a decade, we have also investigated the pathogenesis of celiac disease, an autoimmune disorder of the small intestine, with the goal of discovering therapies and related management tools for this widespread but overlooked disease. Ongoing efforts focus on understanding the pivotal role of transglutaminase 2 in triggering the inflammatory response to dietary gluten in the celiac intestine.
