GxP Bioanalysis · LC-MS / DMPK · ADC Characterisation · Richmond, VA
Principal Investigator across 16 regulated LC-MS/MS programmes for five global biopharmaceutical clients. ADCs, large molecules, small-molecule DMPK, preclinical through Phase III. Every package delivered to submission standard, on time, without a query coming back.
As Principal Investigator at Thermo Fisher Scientific (PPD), I lead 16 GxP-regulated LC-MS/MS programmes for five global biopharmaceutical clients: ADCs, biotherapeutics, small-molecule DMPK, preclinical through Phase III. Every programme has cleared regulatory review without audit findings. The analytical data and reports I generate go directly into client IND and BLA submissions. That’s the job.
Before the CRO, I spent two years building the University of Virginia School of Medicine metabolomics core from nothing. No platform, no SOPs, no reference materials to start with. Two years later: 50+ active research programmes, a 1,610-spectrum MS/MS library on MassBank, papers in Nature Metabolism and Science Advances. Before that, a full phenotypic drug discovery campaign at Nebraska: 43,783 compounds, integrated multi-omics MoA, US patent granted. That work built the instincts the regulated side runs on.
“The best analytical scientists I’ve known could tell you not just what the data said, but what it meant for the programme. That’s the kind of scientist I’ve tried to be.”
I’m available for consulting, advisory work, and senior positions. If your method won’t transfer, your ADC programme is missing an analytical strategy, or your regulatory package keeps coming back with queries, get in touch.

Clients include global biopharma sponsors, bioanalytical CROs, and academic medical centres. These are problems, not techniques.
Your method isn’t behaving, your timeline is slipping, or your team doesn’t have the LC-MS expertise to get a GxP-compliant package over the line. I’ve run 16 programmes covering ADCs, large molecules, and small molecule DMPK. I know where these projects break down and how to fix them.
You need a phenotypic screen designed and validated, or you’ve got hits and need someone who can run the full cascade without cutting corners: dose-response, cheminformatics SAR, multi-omics mechanism work that holds up under scrutiny. I’ve done this at scale. 43K compounds, Z′ = 0.78, patent granted.
Your team ran the experiment. The data came back. Now everyone’s staring at a heatmap wondering what to tell the programme team. I design multi-omics studies around a specific mechanistic question from the start, then build R pipelines that give you an answer, not a figure.
References available on request. Names withheld where NDA applies.
“The analytical data and reports Nishikant delivered went directly into our IND without a single query coming back. His feel for where GxP programmes go wrong, and how to pull them back on track, isn’t something you find often.”
“He built the ADC peptide mapping workflow from nothing and had us exporting MRM transitions to both Thermo and Sciex in under a month. When the method went to the client site, it worked first time.”
“He took our metabolomics core from zero to 50 active programmes in under two years. The SOPs and R pipelines he built are still what the department runs on.”
A 30-minute call is always free. Most engagements are scoped within a week.
Your method is broken or the timeline is slipping. I come in, diagnose it, and deliver a validated, submission-ready method with a full technical report. No retainer.
You need a senior analytical voice on the programme. Someone who can review data, sit in on team calls, and make the right scientific call when the pressure is on. Fixed retainer, rolling.
Named scientific reviewer for regulatory submissions, SAB membership, or expert review of analytical data packages. Written opinions when needed.
Three programmes: what was broken, what I did, and what the client submitted to regulators.

MassBank of North America →Most analytical problems aren’t mysterious. A method that won’t transfer. A screen drowning in false positives. A regulatory data package that keeps coming back with queries. An omics dataset that produced a beautifully formatted heatmap and zero actionable biology. If any of that sounds familiar, let’s talk.
