Principal Investigator

Prof. Alberto Salleo | asalleo@

Professor Salleo recieved his Laurea degree in Chemistry from the University of Rome (Italy) in 1994. He received his M.S. (1998) and Ph.D. (2001) in Materials Science from UC Berkeley investigating optical breakdown in fused silica. He spent 5 years at the Palo Alto Research Center as a postdoc and then a member of the research staff in the Electronic Materials Laboratory before joining the Department of Materials Science and Engineering at Stanford University in 2005.

Postdoctoral Scholars

Dr. Yael Tsarfati | yaeltsa@

Yael received her PhD in Chemistry from The Weizmann Institute of Science (Israel), where she was studying crystallization mechanisms of small organic molecules in aqueous solutions in the group of Prof. Boris Rybtchinski. Prior to that, she was working on perylene diimide/Carbon Nanotubes hybrid materials, as part of her MSc. She joined the Salleo lab in September 2020 as a postdoc, working in collaboration with the lab of Andrew Minor (University of California, Berkeley). Yael’s current research focuses on the structural study of different types of thin films of organic semiconductors using advanced Electron Microscopy techniques. Yael enjoys running outdoors, travelling and spending time with her family and friends. Yael’s twitter account: @YaelTsarfati

Dr. Adam Marks | adammarks@

Adam joined the Salleo group in fall of 2021 as a postdoctoral scholar. He received his M.Sc. degree in Chemistry from Imperial College London in 2016. Following this he joined Prof. Iain McCulloch’s group, completing his Ph.D. in 2020, synthesising OMIEC materials for bioelectronic applications. He then followed the McCulloch group to the University of Oxford, where he was a postdoctoral research associate, focusing on the development of electron transport OMIECs for high performance OECT and thermoelectric devices. He is now a postdoctoral scholar with Prof. Alberto Salleo and Prof. William Chueh at Stanford University. His current research interests are focused on the synthetic development and evaluation of materials for polymeric electrocatalysis. Outside of the lab he enjoys weightlifting and watching sports.

Dr. Gerwin Dijk | gdijk@

After his M.S. in Applied Physics, Gerwin joined ASML where he worked on the development of EUV photolithography systems. He switched careers and received his PhD in Microelectronics for his work on organic bioelectronic devices for cancer treatment with electrical stimulation (Écoles des Mines, France). He joined the Salleo group in the fall of 2021 where he explores polymers for biosensor applications. Gerwin tries to balance life. He is an active person, likes biking, hiking and exploring California, but also enjoys to sit down, talk, drink coffee and read about history.

Dr. Leandro Julian Mele | ljmele@

Julian graduated in electrical engineering and received his PhD from the University of Udine (Italy). During his PhD, he worked on electrochemical modeling of performance and noise for electronic biosensors and bioactuators. Then he continued as a postdoctoral scholar in Prof. Palestri’s group, where he focused on modeling and simulations of conjugated polymers for bioelectronic applications. He joined Prof. Salleo’s group in the fall of 2022 where he is contributing to the understanding of the physical operation of organic devices. Julian loves traveling, playing soccer, cooking, and enjoying time with family and friends.

Dr. Nicholas Siemons | nsiemons@

Following his M.S from University College London, Nicholas received his Ph.D. from Imperial College in Prof. Jenny Nelson’s group where his work focused on atomistic simulations of polymer systems such as Molecular Dynamics, Density Functional Theory, Molecular Metadynamics, and Network Analysis. Nicholas joined the Salleo group in Summer 2023 and is working on electrocatalysis.

Dr. Tyler Quill | tquill@

Tyler received his Ph.D. in Materials Science and Engineering from Stanford University and is currently a postdoctoral scholar in the Salleo group. His research focuses on utilizing organic mixed conductors in neuromorphic devices and electrochemical transistors, as well as studying the structural dynamics which underpin the performance of these materials via operando X-ray scattering and spectroscopic techniques. Outside of the lab, Tyler enjoys camping, hiking, and fly fishing.

Graduate Students
