# A SAI VINATHI on Tal

## Headline

Decision Scientist \| RWE & Oncology Analytics \| Comparator Cohorts, Synthetic Control Arms, RWD \(SAS/SQL\)

## About

I work in Real\-World Evidence, primarily building comparator cohorts and supporting oncology studies for pharma clients using claims and EHR data\. My analyses span incidence, lines of therapy, treatment patterns, baseline characteristics, attrition, and propensity score matching, primarily using SAS and SQL, with R as needed, across data sources such as Flatiron, ConcertAI, COTA, and TriNetX\. One project that stands out involved building a lines\-of\-therapy model using data from 3,000\+ patients across five EMR vendors\. A major part of the work was harmonizing and reconciling inconsistencies across the different sources to ensure treatment sequences and lines of therapy were accurately captured\. I also have strong experience in data validation and QC\. I've developed QC frameworks that were later adopted by other teams, and I've mentored and onboarded 25\+ analysts on RWD study execution\. I work closely with clients and senior stakeholders to translate study objectives into clear analytical plans, and I'm now looking to take on greater ownership of study design, analytical strategy, and client engagement in a senior RWE role\.
