The Hormozi Laboratory



Sarah Hormozi

Associate Professor
Robert Frederick Smith School of Chemical and Biomedical Engineering
Editorial boards of Physical Rev Fluids, Journals of Non-Newtonian Fluid Mechanics, The American Institute of Chemical Engineers and Physics of Fluids.
Faculty Fellow, Cornell Atkinson Center for Sustainability 
Faculty Fellow

Sarah Hormozi received her M.Sc. in Mathematics and her Ph.D. in Mechanical Engineering from the University of British Columbia in 2011. She then completed the most prestigious Canadian postdoctoral fellowship award, sponsored by the Natural Sciences and Engineering Research Council of Canada (NSERC). Currently, she is an Associate Professor of Chemical and Biomolecular Engineering and a graduate field faculty of Mechanical and Aerospace Engineering at Cornell University.
Before coming to Cornell, Hormozi was an associate professor of Mechanical Engineering at Ohio University. The underlying foundation of her work at Ohio was an effort to better integrate the separate fields of colloidal science and non-Brownian suspensions. In spite of their ubiquity, the mechanics of these complex fluids are not well understood. Hormozi’s research has been recognized by a number of awards, including the National Science Foundation CAREER award and the ACS Petroleum Research Fund Doctoral New Investigator Award. Hormozi also serves on the editorial boards of Physical Review Fluids, Journals of Non-Newtonian Fluid Mechanics, The American Institute of Chemical Engineers, and Physics of Fluids. Hormozi is also a Faculty Fellow at Cornell Atkinson Center for Sustainability and a Faculty Fellow in the team of Professor Stephanie R. Thomas,  Faculty in Residence, Low Rises 6&7 Community. Hormozi’s goal is to use science to inspire and empower every individual student to become engaged, confident, and connected leaders in our communities and society.

Postdoctoral Researcher

Dr. Enzo D’Ambrosio-Azzara

Enzo is a physics experimenter who graduated in September 2020. His thesis deals with suspension imaging to measure particle stresses in non-Brownian suspensions in a Couette flow. His Ph.D. work has been rewarded a French thesis prize in rheology and he is an author of two articles published in Journal of Fluids Mechanics (2021) and Physical Review Fluids (2018), respectively.  He has also been involved in the European project PowderReg studying the rheology of cohesive powder before joining Cornell as a postdoctoral researcher.

Ph.D. Researchers

Nishanth Murugan

Nishanth has a bachelor’s degree in Mechanical Engineering from Shiv Nadar University and an M.S. in Applied Mechanics from IIT Madras, India. For his Master’s thesis, he worked on the dynamics and transport in confined living fluids due to the effects of active stresses, auto-chemotaxis, and convective transport. At Cornell, Nishanth will be working on understanding the inertial shear-thickening seen in dense suspensions of non-Brownian particles in viscous fluids.

Sabarish Narayanan

Sabarish has a Bachelor’s degree in Mechanical Engineering and an M.S. in Engineering Mechanics from JNCASR, Bangalore, India. His MS thesis was on transport in low Re hydrodynamics and he has a background in theoretical fluid dynamics and microhydrodynamics. At Cornell, Sabarish will be studying the swimming of flagellated microorganisms in elastoviscoplastic (EVP) fluids like mucous with Prof. Koch and Prof. Hormozi.

Aaron Baxter

Aaron has a Bachelor’s degree in chemical engineering from Case Western Reserve University.  At Cornell, he will study the rheology and fluid dynamics of volume-transition particles and active tracer suspensions for the improved efficiency of geothermal applications.  Outside research, Aaron is an avid golfer, skier, and sports lover.

Mehryar Jannesari

Mehryar has a B.S. in Mechanical Engineering and M.S. in Biomedical Engineering from the University of Tehran, Iran. For his M.S. thesis, he investigated the role of hydrodynamic interactions in enzyme-powered locomotion with low Re in biological media for the purpose of drug delivery. 

Sotoodeh Rassouli

Sotoodeh has a Bachelor’s and an M.S. degree in Mechanical Engineering from the University of Tehran, Iran. In her M.S. thesis, she investigated the imbibition of viscoplastic fluids in fibrous media with the aim of designing a paper-based viscometer for diagnosis applications. At Cornell, she will experimentally study the dynamics of flagellated bacteria in elasto-viscoplastic media. Outside of research, she loves reading books and learning new languages.

Graduate Researchers

Ritwick Sinha

Ritwick has a bachelor’s degree in Chemistry from Cornell. He will be examining geothermal resource efficiency via the rheological characterization of active tracer suspensions. Outside research, Ritwick is an avid rower and a passable cook. 

Sudharshan Kannapadi

Sudharshan is currently an M.S. student at Cornell. He has a Bachelor’s degree in Chemical Engineering from NIT Trichy and graduated with honors. Sudharshan has previously worked in developing a Mechanistic Model for Thromboelastography, and also in Hidden Fluid Mechanics. Outside of research, he loves reading books. 

Undergraduate Researchers

Jonathan Su

Jonathan is a chemical engineering student in the class of 2023. He works as an undergraduate research assistant, primarily focusing on studying the migration of particles in oscillatory flow through a thin channel. Jonathan’s main responsibilities include experimental setup and designing code for image processing. Outside of research, he is a junior representative of the AIChE student chapter at Cornell.
