It always excites me to recommend a suitable scientific tool for researchers to meet their applications — it can be a simple cryostat or a high-end custom-build cryostat. It gives me an immense pleasure when developing a complete measurement system so that researchers can focus on analyzing the data and understanding the underlying phenomenon instead of spending their precious time on building an instrument. I enjoy interacting with researchers and appreciate their service to the scientific community.
Dr. Raghava Panguluri graduated with a MSc degree in Physics from Central University of Hyderabad, India with specialization in electronics and later earned an MTech degree in Cryogenic Engineering from Indian Institute of Technology (IIT) Kharaghpur, India. He received his PhD in Physics (Condensed Matter) from Michigan Technological University in 2001. He then joined the Physics Department of Wayne State University as a Post-Doctoral Research Fellow to establish the Low Temperature Spintronics Lab for measuring spin polarization by point contact Andreev reflection spectroscopy. He continued with his research for more than eight years and gained considerable expertise in measurement tools to perform electrical transport, magnetic, and microscopy studies at cryogenic temperatures. He also received training in a clean room on various measurements and deposition tools required to fabricate nanostructures; developed skills in scanning Hall probe, STM, and AFM and MFM; and worked on a wide variety of materials, including dilute magnetic semiconductors, oxide semiconductors, superconductors, and magnetic materials. He also co-authored approximately 14 peer-reviewed publications.
Dr. Panguluri joined Janis Research in 2010 as a Sales and Applications Engineer and later was appointed Cryogenic Physicist and Applications Engineer and then Senior Cryogenic Physicist and Applications Engineer. In his current position with Lake Shore, he interacts with customers to gather technical requirements, creates new designs to meet customer research requirements, and supports product development. In addition, he prepares documentation for and provides technical support to customers, conducts as-needed product tests, and performs R&D for product feature enhancement.
Dr. Panguluri is currently a member of AAAS and APS.
