Postdoctoral Research Associates / Graduate Students

Dr. Chiranjeevi Barreddi received his Ph.D. from CSIR-Indian Institute of Chemical Technology (CSIR-IICT) Hyderabad, India under the supervision of Dr. Malapaka Chandrasekharam. His research focused on catalysis, biology, and material chemistry. Dr. Barreddi then worked at Aragen Life Sciences for more than five years. There he worked in process research and development to help reduce manufacturing costs of active pharmaceutical ingredients in the early and late phases of development. He is currently a postdoctoral research associate with Medicines for All working on cost-effective approaches in the process development of APIs.

Rama Sayini, Ph.D. brings nearly 6 years of professional experience in the area of synthesis and scale up. Prior to joining M4ALL, he spent two years working as an Associate Scientist (R&D) at Aragen Life Sciences in the CDMO and API Intermediates. He worked in the process development for various API drugs. Most recently, he was completing a postdoc appointment at Wayne State University in organic synthesis. Rama possesses a PhD in Organic Synthesis & Process Chemistry, focusing in the area of total synthesis of biologically active natural products from CSIR Indian Institute Of Chemical Technology (IICT).

Dr. Shrestha brings extensive expertise in organic and organometallic synthesis, catalyst and ligand development, reaction optimization, and GMP-compliant process documentation. He most recently served as a Postdoctoral Researcher at Millipore Sigma, and before that earned his PhD in Chemistry from the University of Toledo. Kendra also completed a research internship at Corteva Agriscience, where he contributed to the design and synthesis of novel agrochemical molecules.

Ramesh Vediyappan, Ph.D. earned his BSc and MSc in Organic Chemistry from Periyar University in Tamilnadu, India. After earning his MSc, he began his career as a Process Chemist with Syngene International Limited, where he had the opportunity to work on various projects for 3 years.  After gaining some industry experience, Ramesh returned to school and obtained his doctorate in Organic Chemistry from Madurai Kamaraj University in Tamilnadu, India.  After graduation, he worked at Aragen Life Sciences (formerly known as GVK BIO) for more than three years as Associate Scientist. During his time with Aragen, he was promoted to Scientific Lead after gaining significant expertise in various MedChem projects.

Juliana has extensive research experience in synthetic organic chemistry, organometallic chemistry, and data science. Most recently, she served as a Postdoctoral Researcher at the University of Utah under the guidance of Dr. Matthew Sigman, where she helped create experimental datasets through high-throughput experimentation (HTE) to investigate structure–activity relationships of ligand–catalysts in copper-catalyzed C–N coupling reactions.

Her work applied both supervised and unsupervised data analysis techniques, including regression, classification, dimensionality reduction, and clustering.

Originally from Brazil, Juliana earned her bachelor’s degree in Chemistry from the Federal Fluminense University and her master’s and doctoral degrees in Organic Chemistry from the Federal University of São Carlos.

In her free time, Juliana enjoys exploring national parks, visiting farmers' markets, and practicing skiing, a sport she has recently taken up.
