Recognizing the transformative potential of automation in structural engineering, Tushar self-taught Python, Rhino, and Grasshopper, developing custom applications for vibration analysis, pile layout automation, and high-rise design. His portfolio showcases practical implementations across diverse project types, from feature stair analysis to SAG mill support structures.
Passionate about democratizing computational tools, Tushar teaches courses at his firm and develops web applications that make complex engineering calculations accessible to his colleagues. His work bridges traditional structural engineering with modern parametric design, demonstrating how automation can enhance both design efficiency and engineering precision.
Preetam Biswas is Structural Engineering Principal at Skidmore, Owings & Merrill (SOM). As both a structural engineer and an architect, Preetam Biswas excels at designing innovative yet simple and constructible systems and led the structural design of several award-winning tall buildings, long-span structures, and small-scale specialty structures. He was drawn to design by the natural world, inspired by the beauty and structural efficiency of a spider’s web and a desire to replicate that efficiency in the built environment—whether it’s a small canopy or a large industrial complex. Approaching his projects from this standpoint, he designs towers, airports, stadiums, and more to celebrate the structure within the architecture.
Preetam has authored and edited numerous technical publications and served as editor and lead author of the American Society of Civil Engineers’ (ASCE) Design and Performance of Tall Buildings for Wind. He actively participates in various committees, currently serving as the Chair of ASCE Tall Buildings Committee and member of the Structural Engineers Association of New York (SEAoNY) Code Advisory Committee. He also serves as an academic advisor at Syracuse University and New York University.
Amory Martin is a Managing Engineer at Exponent in the Civil & Structural Engineering practice. Dr. Martin specializes in investigating structural failures, disaster risk management, and earthquake engineering. He has experience in dynamic analysis of complex structural systems, computational simulation of structures subject to extreme loads, and optimization of innovative seismic protective systems.
As a consultant, Dr. Martin has served on projects involving structural collapse, seismic performance of highway bridges, multi-hazard risk analysis, and construction defects and code compliance issues of high-rise buildings. His expertise includes structural optimization, statistical analysis and data-driven techniques related to hazard analysis and seismic performance of steel and concrete structures.
Dr. Martin developed seismic capacity design methods for steel rocking braced frames and validated them through nonlinear response history analysis. He developed structural topology optimization algorithms for buildings under seismic excitation and implemented the procedure for large-scale 3D structures using high-performance computing. He also developed optimization algorithms for nonlinear dampers of stacked rocking systems using a novel ground motion selection procedure. Dr. Martin is an Adjunct Professor at New York University, where he teaches a graduate course on structural dynamics.
Daniel Ki joined Severud Associates as an engineer in 2015 and in 2019, progressed to senior engineer. In 2021, he advanced to associate. His decade of design experience has yielded a thorough grasp of structural analysis, including specialized areas such as parametric design and employing computational methods to automate design and related tasks. Dan’s major projects include 100 Vandam Street in Manhattan, a residential tower built over and within an existing building, Halletts Point Building 10, a residential building in Queens, and 43 Gatehouse Road, a commercial building in Stamford, Connecticut.
Dan was co-editor of Cross Sections, the quarterly newsletter of the Structural Engineers Association of New York, from 2019 to 2021.
Dan is licensed as a structural engineer in Nevada and as a professional engineer in New York. He earned a Bachelor of Science in civil engineering and Master of Engineering in structural engineering from Cornell University.
