Hannah Stuart received her BS in Mechanical Engineering from the George Washington University in 2011. She then completed her MS and PhD in Mechanical Engineering at Stanford University in 2013 and 2018 respectively.
Research Description:
Professor Stuart’s research interests include: Dexterous manipulation; Bioinspired design; Soft and multi-material mechanisms; Skin contact conditions; Tactile sensing and haptics.
Mobile robots face a rapidly expanding range of potential applications, including remote exploration, search-and-rescue and household assistance. In many of these cases, the focus of interaction is via the robot’s end-effectors. However, current manipulators have limited capabilities in comparison to their biological counterparts. Our group is interested in improving robot dexterity through building end-effectors with embodied intelligence and robustness, especially for challenging submerged or wet environments. This includes the design of (1) novel grippers and hands, (2) touch perception for autonomous or teleoperated interventions and (3) bioinspired manipulation strategies. This vision includes the advancement of relevant design analysis tools and the validation of concepts by applying technologies in the field.

Oliver M. O’Reilly is a professor in the Department of Mechanical Engineering and Interim Vice Provost for Undergraduate Education at the University of California at Berkeley.
He received his B.E. in Mechanical Engineering from the National University of Ireland, Galway (NUIG). Subsequently, he received his M.S. and Ph.D. degrees in Theoretical and Applied Mechanics from Cornell University. At Cornell, he studied under Phil Holmes and Frank Moon. After spending two years as a postdoc at the Institut für Mechanik at ETH-Zürich under Jürg Dual, he joined the faculty in Mechanical Engineering at Cal in 1992. He has previously served as the Chair and Vice Chair of the Berkeley Division of the Academic Senate and as an Associate Dean for Graduate Education in the Division of Computing, Data Science, and Society.
His interests span the fields of continuum mechanics and nonlinear dynamics. He has a broad range of specializations including directed (or Cosserat) theories of deformable bodies, constrained rigid body dynamics, contact mechanics, linear and nonlinear vibrations and linear and nonlinear dynamics of deformable bodies. He has applied these interests to a range of applications including soft robots, MEMS resonators, brake squeal, the dynamics of toys, motorcycle navigation, axially moving media, artificial and natural satellites, spinal kinematics and vehicle collision dynamics.
O’Reilly has coauthored over 100 archival journal articles, written three textbooks, coauthored a monograph, and is a co-inventor on two patents. He has also received multiple teaching awards including U.C. Berkeley’s Distinguished Teaching Award in 1999, the Pi-Tau-Sigma Professor of the Year Award in 2003 and the Tau-Beta-Pi Outstanding Faculty of the Year Award in 2013.

Simo A. Mäkiharju is an Assistant Professor at UC Berkeley. Prof. Mäkiharju’s undergraduate studies were in Energy Technology at the Lappeenranta University of Technology, Finland. In 2005 he received his Mechanical Engineering M.Sc. from the Ohio State University and his Ph.D. in 2012 from the University of Michigan. His graduate research focused on the reduction of hydrodynamic drag by gas injection and the development of a time-resolved x-ray densitometry imaging system for the study of multiphase flows. He continued at the University of Michigan as a Post-Doctoral Research Fellow (2012-2014) and as an Assistant Research Scientist (2014-2015) investigating single- and multiphase flow mixing in channel flows while continuing the development of x-ray based 2D and 3D flow measurement techniques. Starting as an Assistant Professor at UC Berkeley in January of 2016, he is continuing to pursue his research interest in advancing the physical understanding of high-Reynolds number single- and multiphase flows through experimental research, primarily through the development and use of advanced experimental techniques.
Research Description:
One of the central objectives of Professor Mäkiharju’s research is to advance the physical understanding of high Reynolds number single- and multiphase flows primarily through experimental research, and through the development and use of advanced experimental techniques. Multiphase flows are encountered in almost every aspect of modern life, including offshore applications, biological flows, energy production, chemical processing, and naval hydrodynamics. Specific topics Professor Mäkiharju has worked on include the reduction drag on marine vehicles, mitigation of damage and noise caused by cavitation in naval and industrial applications, and efficient handling of single- and multiphase flows in energy production applications.
