Tim Weihs  [Biosketch]

weihs@jhu.edu

Dr. Weihs has over 20 years experience in the fabrication and characterization of solid materials with a focus on thin films, structural materials, hard biomaterials, and reactive materials. He joined the Department of Materials Science and Engineering at Johns Hopkins in 1995, but took a three year leave of absence in 2002 to co-found and serve as CEO of Reactive NanoTechnologies. Prior to joining Hopkins Dr. Weihs earned a B.S. from Dartmouth College, an M.E. from Thayer School of Engineering and a Ph.D. from Stanford University. He also completed postdoctoral research positions at Oxford University and Lawrence Livermore National Laboratory.

  Postdoctoral Researchers

KerriLee

Kerri-Lee Chintersingh

kchinte1@jhu.edu

Kerri-lee Annique Chintersingh is a former Process Control Engineer from the Caribbean island, Jamaica. She joined the Weihs group in October 2019. She graduated with a B.Eng in Chemical Engineering from the University of Technology, Jamaica and received her PhD in Chemical Engineering from NJIT. Her current research is funded by DTRA, and focuses on tuning metal and metallic composites as reactive materials for chemical and biological agent defeat. Her research utilizes principles from powder technology, kinetics, and machine learning to better understand complex reactions mechanisms, particularly dual- phase combustion. As a part of the Weihs group, she intends to expand her research by applying concepts from her energetic materials field to design metallic components for structural and biomedical applications. Kerri is actively involved in several community-related outreach efforts including mentoring, teaching high school students, and donating her very own hand-crafted crocheted blankets. She loves painting, travelling, and learning about new cultures and new languages.
