Abstract: In this seminar, we will first review the key concepts relevant to the generation and detection of terahertz electromagnetic waves in a standard Terahertz Time-Domain Spectroscopy (THz-TDS) technique. We will describe the technological advancement made in recent years in our laboratory to bring the THz technology from the laboratory to the bed-side. We will then discuss a new variation of the THz-TDS technique, recently invented in our group, dubbed Terahertz Time-Domain Polarimetry (THz-TDP), which allows for real-time detection of the polarization direction of the terahertz electric-field without the need for any external polarizers. Finally, we will explore applications of both THz-TDS and THz-TDP techniques in biomedical imaging. These applications range from diagnostic imaging of skin burns, melanoma and breast cancer to early-diagnosis of corneal diseases such as Fuchs' dystrophy, and early detection of Glaucoma. The goal is to introduce the diverse set of biomedical applications of terahertz imaging being pursued today.
 

Bio: Dr. Arbab received his PhD in Electrical Engineering and Nanotechnology in 2012 from the University of Washington (UW). In his dissertation, he focused on developing the terahertz spectroscopy technique as a new diagnostic modality for triage of burn injuries. He was then awarded the inaugural Applied Physics Laboratory (APL) Director's Distinguished Post-Doctoral Fellowship, designed as a path to independence for young investigators. During his postdoctoral appointment, he continued his work on developing terahertz spectroscopic and polarimetric technologies for biomedical imaging and non-destructive testing applications. He held a senior research scientist position at the APL-UW until September 2016, when he moved to the Department of Biomedical Engineering at Stony Brook University (SBU), where he started the new Terahertz Biophotonics Laboratory. His research at SBU has continued to focus on the invention and application of portable and handheld terahertz scanners for various imaging applications under funding support from the NIH, NSF, DOD and industry. His research interests also include millimeter-wave polarimetry, non-linear and ultrafast optics, and modeling the propagation and scattering of terahertz waves in biological tissue. He is a co-inventor of 4 patents and patent applications.
