As a postdoctoral fellow in the College of Sciences, his work brings together theory and computation to better understand the dynamics of living tissues.\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003ESadjad investigates how living and soft materials store what is known as \u201cmechanical memory,\u201d the idea that tissues can \u201cremember\u201d past forces and experiences. His research focuses on how living tissues change shape, respond to mechanical force, and acquire new behaviors over time. Working at the intersection of theoretical and computational soft matter physics and biophysics, he studies how local cell-to-cell interactions can give rise to large-scale tissue behaviors, particularly during processes like morphogenesis. His work is driven by a broader question: how can living systems be trained or guided to achieve targeted responses? By understanding how tissues adapt to past experiences, Sadjad aims to uncover principles that could one day inform advancements in health, medicine, and bioengineering.\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003ESadjad investigates how living tissues sense forces, adapt to them, and even \u201cremember\u201d them over time. This matters because these physical responses help determine how biological tissues grow, heal, and function, and understanding them could eventually inform medicine, bioengineering, and the design of adaptive materials. A major focus of his research is morphogenesis, the process by which cells move, reorganize, and change shape to build the structures of a living organism. What makes this process so remarkable is that living tissues are not shaped the way we shape most everyday materials: if we want to make a beautiful clay sculpture, an artist has to mold it by hand from the outside. In living systems, by contrast, there is no outside sculptor guiding each step. Instead, cells interact locally with one another, and those local interactions can collectively generate complex, functional forms. Using physics-based theory and computer simulations, Sadjad investigates how these simple local interactions give rise to large-scale tissue behaviors, with the broader goal of understanding how living systems can develop targeted properties and responses\u2014and how those same ideas could help inspire the design of novel bio-inspired materials.\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003E\u003Cstrong\u003EThe Road to Georgia Tech\u003C\/strong\u003E\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003EAfter completing his Ph.D. in chemical and biomolecular engineering from Rice University in 2021, Sadjad pursued postdoctoral research jointly at Syracuse University and the University of Pennsylvania, where he continued developing his interdisciplinary approach to soft matter physics and biophysics. He joined Georgia Tech in 2025, drawn by its strong community in physics and living systems.\u003C\/div\u003E\u003Cdiv\u003E\u201cGeorgia Tech was the natural next step for me because it offers an exceptional environment for soft matter, biophysics, and interdisciplinary physics,\u201d he shares.\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003EHis interests, centered on understanding biology through the lens of learning and adaptation, aligned strongly with Georgia Tech\u2019s Physics of Living Systems (PoLS) community, an NSF-funded interdisciplinary program that studies biology through a physical framework.\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003E\u201cI was drawn by the opportunity to work with \u003Ca href=\u0022https:\/\/shiladitya-banerjee.com\/\u0022\u003EProfessor Shiladitya Banerjee\u003C\/a\u003E, whose research has a strong overlap with my own interests in how cells and tissues move, respond to forces, and organize into larger patterns and behaviors,\u201d shares Sadjad.\u003C\/div\u003E\u003Cdiv\u003EReflecting on his decision to continue his research at Georgia Tech, Sadjad describes the Institute as \u201ca vibrant and collaborative place,\u201d adding that Atlanta has been a \u201cwonderful city to live in\u201d while building this next stage of his research career.\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003E\u003Cstrong\u003ELife Outside the Lab\u003C\/strong\u003E\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003EA typical day for Sadjad blends deep focus with active collaboration.

Playing tennis has become one of his new favorite pastimes and serves as a reset after long days of research. He also enjoys long walks and hikes, since he views time in nature as a form of meditation. Local trails like Arabia Mountain provide a peaceful escape, and walks along Atlanta\u2019s Beltline Eastside Trail, as well as visits to Persian restaurants, help him stay connected to the city and his cultural roots.\u003C\/div\u003E\u003Cdiv\u003E\u0026nbsp;\u003C\/div\u003E\u003Cdiv\u003EThrough his work and daily routines, Sadjad embodies the spirit of interdisciplinary discovery, bridging physics and biology to better understand how living systems evolve, respond, and adapt.
