Venkat Keshav Chivukula
Postdoctoral Researcher


Venkat Keshav Chivukula

My exciting journey began halfway around the world in Mumbai, where I completed my bachelor's in mechanical engineering. I came to the University of Arizona to pursue my master's in mechanical engineering, which I completed in 2010. Throughout my master's education I was increasingly drawn towards applying the mechanical engineering concepts to biological applications, and this culminated in my pursuing a Ph.D. degree in biomedical engineering from the University of Iowa, where I researched novel methodologies to model blood cells at the micro-scale. I spent a year in Portland,OR at the Oregon Health and Science University (OHSU) researching hemodynamics in cardiac development, before moving to the UW. I am currently involved in determining the influence of hemodynamics on efficacy of heart failure therapies, and am also working on investigating blood flow in intracranial aneurysms. Outside of the lab, I love going on hikes, long drives, cooking (and eating good food!), painting, reading, and having philosophical discussions.

Craig Hill
Postdoctoral Researcher


Craig
            Hill

Craig joined UW and the lab in December 2015. He received his PhD from the University of Minnesota in 2015 investigating the interactions between complex topography and sediment transport and the impact they have on the performance and wake characteristics of axial flow marine renewable energy systems. Prior to graduate studies at the University of Minnesota, Craig received a BA in Geology from the University of St. Thomas, and worked as a Research Engineer at St. Anthony Falls Laboratory in Minneapolis, MN from 2006-2012 on various projects ranging from physical model studies of hydraulic structures, fluvial geomorphology and stream stabilization/restoration studies, lab and full scale wind energy research, and modeling of hydrokinetic energy systems. Craig's current research utilizes both lab and field scale turbines and aims to improve the survivability and performance of marine energy systems using active control strategies, as well as continue to investigate the impact marine energy systems have on the environment.

Teymour Javaherchi
Postdoctoral Researcher


Teymour
            Javaherchi

Teymour Javaherchi, is a full time instructor at Everett Community College, as well as a postdoctoral researcher in Mechanical Engineering at the University of Washington in Seattle. His research interests involve energy and fluid. Currently he is working on numerical simulation of tidal turbines, which convert the raw energy of tides (driven by the gravitational pull of the sun and moon on the oceans of the earth) to useful energy (mechanical power and electricity). He uses commercial software packages, such as FLUENT and Star CCM+, for doing a comprehensive numerical simulation of the flow behavior around the tidal turbine blades.

Teymour did his undergraduate in the Sharif-Aachen (SUT-AcUAS) cooperation program in Mechanical Engineering. He studied for three years at Sharif University in Iran and then completed his bachelor thesis at Aachen University of Applied Science in Germany with emphasis on understanding and measuring reflectance and transmission degree of solar panel surfaces. He continued his education in the Master of Science program at Aachen University of Technology (RWTH-Aachen) in Germany. During his studies there, he had the opportunity to go to the University of Pennsylvania and after one semester there he became intrigued with the work done by professor Aliseda at University of Washington and joined his research group at fall 2008.

Teymour's main goal is to make significant contributions in the production of clean energy for mankind through collaborative research on the fluid aspect of energy in order to improve the efficiency of current technology for renewable energy sources such as tidal energy.

Michael Barbour
Research Assistant


Michael Barbour, PhD Candidate

Mike completed his B.S. in Mechanical Engineering at the University of Vermont in 2012. He joined the University of Washington to do a PhD in fluid mechanics that Fall. His research is focused on understanding the hemodynamics of blood flowing in intracranial aneurysms, and in particular, he performs numerical computations on virtual models of patient blood vessels inside the skull (on or around the Circle of Willis) to develop a predictive algorithm that determines the success of endovascular treatment for intracranial saccular aneurysms: coiling and/or stenting. He works within a multidisciplinary collaboration between fluid mechanicians and neurosurgeons that apply state of the art fluid mechanics experiments, computational simulations and in vivo imaging (CT rotational angiography and intravascular Doppler ultrasound) to tackle this problem that has puzzled biomechanics and medical experts for several decades. This effort is funded by NIH (NINDS 5R01 HL115267) and has been published in multiple manuscripts ([1], [2], [3])


Alicia Clark
Research Assistant



Alicia
            Clark, PhD Candidate

Alicia graduated from Lafayette College with a BS degree in Mechanical Engineering in 2011. She joined the University of Washington as a PhD student in 2011 and, within her first year in the Multiphase & Cardiovascular Flow Lab, she was awarded the National Science Foundation Graduate Research Fellowship. In February 2016, she passed the PhD Candidancy Exam and is finishing her PhD in Mechanical Engineering with a planned defense in 2017.

Alicia's research focuses on the dynamics of microbubbles injected into the human circulation. In particular, she conducts experiments and analysis to understand the forces that determine the trajectory of microbubbles in arteries and veins, where they are subject to complex forces from the high Reynolds number blood flow and the Bjerknes or radiation force from an ultrasonic acoustic field.
