Currently Mr. Ashiqur is working as a Research Associate at Semiconductor metrology lab in Arizona State University (ASU). His present research focuses on semiconductor materials and device characterization. Previously he served as a Graduate Research Assistant at ASU 'Nanoscience & Biotechnology Lab'; prior that worked in 'Center for Advanced Photovoltaics and Sustainable Energy' laboratory of South Dakota State University (SDSU).
Before joining ASU, Ashiqur worked on cost effective perovskite solar cells and heavy metal ion sensor. Later at ASU, he worked on solid-state nanopore sensor fabrication and biomolecule sensing. He was also engaged in developing the next-generation DNA based highly-secured memories through collaborative work. He has published several research articles in different prestigious Journals and also presented his works in international conferences.
