Applied Computing

Dr. Nathir Rawashdeh, Assitant Professor

Dr. Nathir Rawashdeh’s research interests include autonomous vehicles, mobile robots, mechatronics, applied artificial intelligence. His lab focuses on unmanned vehicles, image processing, sensors, and their applications. His team develops and deploys mobile robots for different applications, image processing for depth sensing using Lidar/Radar/RGBD and thermal imaging, simulation of environments for robots, sensor fusion, and custom electronics. His lab offers the opportunity to learn about mobile robot applications and their sensory and control programming and is aimed at improving accessibility to these technologies across various fields.

Specifically, Dr. Rawashdeh's Applications include a teleoperated robot for the disinfection of rooms using ultraviolet light towers. The radiation damages the DNA of viruses including the Coronavirus and renders it incapable of replication. To perform experiments using UV lights, the radiation intensity, and spatial distribution must first be measured and modeled and understand the light metering equipment and safety gear required. Other platforms perform simultaneous location and mapping (SLAM) using the Robot Operating System (ROS). SLAM is imperative for every mobile robot to perform navigation. ROS is a popular open-source control environment used to implement SLAM and other algorithms. The implementation of artificial intelligence (AI) features is also of interest. A rescue robot may, for example, use AI on a camera input to recognize an injured person or special objects. The lab also offers various sensors for experimentation and creative use including, laser range finders, short rage radars, thermal imagers and common cameras.

Biological Sciences

Dr. Rupali Datta, Professor

Dr. Datta’s primary research interest lies in the application of plant biochemistry, genetics, molecular biology and microbiology in solving environmental problems,using phytoremediation, plant-microbe interactions and bioremediation. Dr. Datta’s research involves the study of interactions between plant, soil, microbial and water systems to understand the mechanisms of uptake and detoxification of specific environmental contaminants in biota from two broad angles – biochemistry and genetics.

Specifically, Dr. Datta’s current research focus is on the study of bioavailability of metal and organic contaminants in aquatic media and the potential of using plants to remediate contaminated sites, mediated by microbes. Dr. Datta actively collaborates with environmental geochemists, soil scientists, microbiologists and analytical chemists. Dr. Datta also works on the bioavailability of contaminants using in-vitro and in-vivo models. She has also been working on the remediation of antibiotics, TNT, RDX, and petroleum hydrocarbons in soil and water and in developing “green technology” as part of an environmental R&D, SIROM Scientific Solutions, LLC , New Jersey. Combining field, greenhouse, and laboratory data, she investigates the mechanisms of contaminant bioavailability, availability to plants, the kinetics of contaminant uptake in plants under various conditions and studies the molecular mechanisms of contaminant uptake and detoxification by accumulator and other high biomass plants, including crop plants using "omics" technologies. She also works on health effects of metals (arsenic and lead) in human cell culture and animal systems in collaboration with biomedical faculty.

Dr. Bruce Lee, Professor

The Lee group research is focused on applying biologically-inspired molecular designs with chemistry, polymer engineering and materials science principles in developing advanced and functional materials for various biomedical applications. Current projects include applying biomimetic structural designs to create tough hydrogels that can potentially function as tissue adhesives or extracellular matrices for tissue repair and regeneration, and coatings to control biointerface of biomaterials that can prevent non-specific absorption of proteins, cells, and bacteria.

Prior to joining Michigan Tech, Dr. Lee helped found a start-up company, Nerites Corporation, which aimed at commercializing biomimetic bioadhesive and antifouling technologies. Nerites Corporation was acquired by Kensey Nash Corporation (part of Royal DSM) in 2011.

Dr. Lee was awarded the 2016 Young Investigator Award by the Office of Naval Research.
