# Parikshit D. > Experienced Professional | Optimization Under Uncertainty | Non-linear Estimation | Machine Learning Location: San Francisco Bay Area, United States Profile: https://flows.cv/parikshitd I am a software developer and researcher with experience in state estimation, localization, guidance, navigation and control of highly complex autonomous systems. Extensive knowledge and experience on positioning and GNC algorithms, including Kalman filters, particle filters, Monte Carlo methods, PID, MPC and LQR. I have procured funding, led and successfully completed several projects for NASA and DoD on these topics. I have very good knowledge of C++ and Python and good grasp over C. ## Work Experience ### Software Engineer @ Software Company Jan 2025 – Present | San Francisco Bay Area ### Software Engineer, Localization Calibration and Mapping @ Zoox Jan 2022 – Jan 2025 | Foster City, California, United States CLAMS: localization calibration and mapping. Implementing the SLAM pipeline at Zoox. ML/AI in pose estimation. ### Staff Software Engineer @ Luminar Technologies Jan 2020 – Jan 2022 | Palo Alto, California, United States Localization calibration and mapping. Lidar and visual inertial odometry. Graph SLAM based smoothing and mapping, structure-from-motion, lidar odometry and mapping, lidar-inertial SLAM/odometry, lidar-IMU and lidar-lidar calibration. Use of Factor Graphs to achieve the aforementioned tasks. Software quality maintenance and adherence to ASPICE and ISO-26262 safety standards. ### Principal Investigator @ Optimal Synthesis Inc. Jan 2019 – Jan 2020 | Los Altos, California, United States Projects: 1. Principal Investigator for a GPU based high-performance Monte Carlo simulator for fire control schedulers using radar feedback. 2. Signal processing and state/parameter estimation software development for a low-cost INS/IMU platform for navigation without GNSS/GPS fix. ### Research And Development Scientist @ Optimal Synthesis Inc. Jan 2014 – Jan 2019 | San Francisco Bay Area Projects: 1. Back-end developer for a gate-to-gate large-scale concurrent air traffic simulator for National Airspace System. (C++/CUDA) 2. Developed a C++-based tool to generate multiple paths from origin to destination using a time-dependent A* search on the National Airspace System (NAS) (best paper in Aviation in 2018). 3. Developed a MPC-based tool for real-time guidance of interceptors to kill maneuvering missiles using Radar feedback. 4. Developed a C++ based large-scale linear optimization routine using Dantzig-Wolfe decomposition for integrated arrival departure enroute and surface traffic flow operations. 5. Developed software for cooperative navigation of multiple SUAVs in GPS/GNSS denied environments using inter-UAV localized range measurements and partial GPS/GNSS access. 6. Developed a GPU and particle filtering based multi-target tracking tool for hypersonic aerial vehicles in presence of high sensor noise. 7. Developed a multi aircraft detection and tracking framework for ramp area surveillance. ### Postdoctoral Associate @ Duke University Jan 2013 – Jan 2014 | Raleigh-Durham, North Carolina Area Solved a large scale inverse problem to determine the material properties of arteries using ultrasonic excitation. Used sparse-grid collocation interpolation to construct surrogate models of arteries which was then used as constraints to an L2 optimization problem. Skills and responsibilities: CI/CD with a large C++ repo. ### Associate Researcher @ INRIA Jan 2011 – Jan 2013 | Grenoble Area, France Uncertainty quantification, stochastic optimization, development of scalable algorithms for land use and transportation systems. calibration and validation of land use and transportation models.
