Devaki A. Kelkar, PhD.


Dr Kelkar's research training at CCMB, Hyderabad was in fluorescence and other spectroscopic techniques to study lipid protein interactions. As a post-doc, Dr. Kelkar switched gears to more complex proteins, initially studying molten globule states of pro-lactin and spectrin at CCMB and at OHSU, Portland worked on the co-translational folding of the RFP variant, m-cherry. On her return from USA, she worked at a private data curation firm in Pune  as a Domain Expert. There she worked on designing and building databases for data curation of data relationships such as protein mutations and phenotypes, SNP-disease data, and microbiome data among others. In addition, she used R to create scripts to semi-automate the data curation process. Along with other members of the team, she developed a product to gather metadata for datasets in NCBI GEO for specific search words with filters and used text mining to classify GEO metadata as test/control cases. This work was presented as a poster at the 10th International Biocuration Conference.  At Prashanti Cancer Care Mission she has built a data entry and management system to faciliated the creation of  a database of breast cancer patients. She has created the database schema based on input from the clinicians at Prashanti and used that to create a systematic data entry portal with restricted vocabulary and partially in built data verification. The portal is written in python with a command line interface linked to a local SQLite database. This is in the process of being migrated to a server based mySQL database that can be linked to IHC and fluorescence imaging data at collaborative labs at IISER, Pune. She is also involved in building workflows for analysis of expression and mutation data from publicly available datasets such as TCGA and METABRIC and their correlation to clinico-pathological parameters.
