SMART-on-FHIR clinical AI evaluation workstation tested against Epic and Cerner FHIR R4 production sandboxes, with a Bayesian causal inference engine built to enforce citation provenance in AI-assisted clinical summaries. Manuscript under revision at Scientific Reports (Nature Portfolio); preprint on medRxiv.

Clinical evidence retrieval platform integrating thirteen biomedical APIs (PubMed, ClinicalTrials.gov, Cochrane, CrossRef, WHO IRIS), with a PRISMA-compliant systematic review generator implementing GRADE and RoB 2.0 methodology.

A separate clinical decision-support platform, distinct from AuditMed, built around a knowledge base of 500+ real clinical guideline files from 227 publishing societies, an inference engine, and SMART-on-FHIR integration.

An umbrella suite of browser-based computational chemistry and informatics platforms, including NeuralDock Pro (molecular docking for structure-based candidate screening), GenomeForge (genomics and protein visualization), and AntibodyForge Pro (computational antibody engineering, NeRF geometry engine + ESMFold).

A FastAPI/WebSocket clinical education platform integrating real data sources (NADAC, CMS Part B ASP, ClinicalTrials.gov, openFDA) — built to bring clinical-decision infrastructure to a Bahamian teaching context.

Washington DC VA Medical Center — a 30-patient retrospective chart review, a GRADE-style Pharmacy & Therapeutics committee presentation, and a CPRS implementation memo demonstrating translational evidence synthesis and formulary-decision support.

Virginia Peninsula Community College — designs and delivers college-level chemistry curriculum as a VCCS-credentialed online instructor: General Chemistry, Organic Chemistry, Biochemistry/Chemical Biology, and Drug Discovery.

Taught undergraduate chemistry, building on family ties to the institution and extending his commitment to making rigorous science education accessible in The Bahamas.

Howard University College of Pharmacy — mentors pre-pharmacy students on pharmaceutical sciences and professional development.

Howard University College of Pharmacy — recruited and hosted Dr. Brian Kobilka (Stanford, 2012 Nobel Laureate in Chemistry), Dr. Robert Langer (MIT), Dr. Emery N. Brown (MIT/Harvard), and Dr. L.C. Campeau (Merck).

A browser-based role-playing game that teaches pharmacy concepts through interactive clinical scenarios — turning case-based learning into a game students can play through.

Sole author; forewords by Dr. Robert Langer (MIT) and Deputy Permanent Secretary Deveaux; a 300-question companion workbook. Begun in 2021 as an accessible high-school chemistry handbook and developed over several editions since — including in response to classroom resource loss following Hurricane Dorian, when it took on its present Bahamian, BGCSE-aligned form, with proceeds supporting hurricane relief. Now proposed to The Bahamas' Ministry of Education as a national adoption initiative reinvesting profits into school science-lab infrastructure.

On David's path from a 2019 Taylor biochemistry degree into the Howard University PharmD program, his work as a pharmacy intern and researcher, and founding The New Chemist's Podcast Group to introduce others to chemistry and scientific careers.

By Barbara Walkin — on the BGCSE-aligned textbook's use of real Grand Bahama landmarks as teaching tools, built four years after Hurricane Dorian destroyed school resources, with support from Dr. Robert Langer, co-founder of Moderna.

A profile of David's balance of academics and outreach — advanced degrees in biochemistry and chemistry, authored textbooks, and a podcast platform featuring prominent scientists and leaders — framed around a commitment to accessible pharmaceutical care for underrepresented communities.

By Sholnn Z. Freeman — profiles the making of Bahamian Superheroes, a graphic-novel-style chemistry textbook set in real Grand Bahama locations, built to rebuild educational resources lost to Hurricane Dorian.

Featured as one of the American Chemical Society Bridge Program's first Fellows (2020), spotlighted for authoring a chemistry textbook that blends core concepts with graphic-novel storytelling to make science more approachable for high schoolers.
