Dr. Sravya Tekumalla

Dr. Sravya Tekumalla is currently a Principal Investigator in Nanyang Technological University, Singapore, where she works as a Presidential Postdoctoral Fellow. In addition, she also leads a small team of staff and students working in the domain of metal additive manufacturing (commonly known as 3D printing).

Her current research interests include engineering microstructures via alloy design and process control to develop next-generation metallic materials with tailored property profiles. One such application of her current work is in the design and development of novel, low modulus-high strength-durable titanium alloys intended for biomedical applications (in components such as implants) that have the potential to transform the landscape of the biomedical industry.

Dr. Sravya Tekumalla is a Materials Scientist, working on unravelling the potential of different novel and advanced metallic materials for several applications suiting different requirements including that of aerospace, automobile, biomedical and electronic applications.

She holds a Doctor of Philosophy from the National University of Singapore (NUS) for her work on Futuristic In-Situ and Ex-Situ Approaches for Synthesis of Superior Magnesium Nanocomposites. She later went on to do a Postdoctorate at NUS on Ignition/Flame Resistant Materials for Aerospace/Defense Applications. She is currently working on Additively manufactured Beta type Titanium alloys for Biomedical Applications as part of her NTU Presidential Postdoctoral Fellowship. 

She has co-authored 1 book, 2 book chapters, and published over 20 scientific articles in international peer-reviewed journals in the field of metallic materials traversing the space of processing-microstructure-property-performance relationships (also referred to as the materials science paradigm).
