Research & IP

I study how water and environmental-health interventions perform from measurement to delivery. My work combines analytical chemistry, evidence synthesis, quantitative and mathematical modeling, field implementation, and service-delivery research to understand what works, for whom, at what cost, and under which operating conditions.

My approach to research

I begin by defining the decision a study needs to inform: the population, the outcome that matters, the comparison, the time horizon, and the evidence that would change the course of action. I combine published research with laboratory, operational and field data, then build a transparent quantitative model to show how the pieces connect and which assumptions drive the result. The final step is to compare the model with what happens in practice and use that evidence to revise the product, service, measurement plan, or next research question.

  1. 1Frame the decisionDefine the problem, population, comparison, outcome, time horizon and the decision the work must inform. Identify what result would change the answer before choosing the method.
  2. 2Build the evidence chainTrace how an intervention is expected to move from design and delivery to use, performance and final outcomes. Synthesize the strongest available studies and separate measured evidence from assumptions.
  3. 3Quantify the problemUse statistical analysis, mathematical and process models, and cost or lifecycle comparisons to estimate scale and trade-offs. Make denominators visible and test how the conclusion changes under plausible assumptions.
  4. 4Test it in practiceCompare laboratory and study expectations with field performance, user behavior, maintenance, workflow adoption and operational data. Investigate disagreements among data sources and look for conditions the original model missed.
  5. 5Update the design or decisionTranslate findings into a choice to scale, redesign, measure differently, investigate further or stop. Continue monitoring after implementation and feed the results into the next research question.

Each answer sets up the next question.

How the approach connects my work

EveryWaterGeorge Mason UniversitySafe Life
Question How can a membrane system remain usable, maintainable and affordable outside the laboratory? How much calculated exposure and mixture toxicity is hidden by reporting limits and common substitutions for non-detects? Which home and workflow conditions can the care team identify and address to improve delivery and outcomes?
Evidence Membrane tests, production yield, unit cost, maintenance, partner delivery and user feedback Trace DBP measurements, reporting limits, censored-data methods, distribution-system samples and toxicity-weighted calculations Clinical, utilization, workflow, quality, hospitalization and structured home-environment data
Decision Revise product configuration, instructions, manufacturing priorities, maintenance or delivery model Improve analytical and reporting methods so exposure comparisons are less biased Retain, redesign or investigate clinical pathways, coordination practices, documentation tools and follow-up workflows

Enhanced formation of brominated and nitrogenous disinfection byproducts in drinking water disinfection with chlorocyanurates

Co-author · Original research · Environmental Science & Technology · 2026

QuestionDo chlorocyanurates produce a safer disinfection-byproduct mixture than conventional chlorine when regulated and unregulated compounds are considered together?
ApproachWe compared several chlorocyanurate formulations with conventional chlorine across regulated and unregulated byproduct classes and estimated the toxicity of the resulting mixtures.
FindingChlorocyanurates reduced regulated byproducts by approximately 10% to 50%, but increased bromine incorporation by 50% to 200% across most classes and produced higher calculated toxicity under most tested conditions.

Evaluating the impact of emerging contaminants on membrane performance in ultrapure-water production for semiconductor manufacturing

First author · Evidence synthesis · IEEE Transactions on Semiconductor Manufacturing · 2026

QuestionHow do emerging contaminants affect the performance of reverse osmosis, nanofiltration and ultrafiltration in ultrapure-water production?
ApproachWe conducted a structured review and evidence synthesis of 31 studies covering PFAS, pharmaceuticals and personal-care products, semiconductor-process organics, and micro- and nanoplastics. The review is reported using the PRISMA framework.
FindingThe synthesis identified strong rejection for many long-chain compounds, a remaining challenge for short-chain PFAS, and material throughput losses when ultrafiltration encounters some semiconductor-process organics.

Impact of contaminated water on the prevalence of diarrheal diseases in children

First author · Cross-sectional observational study · Frontiers in Health Informatics · 2024

QuestionHow were household microbial water quality and recent diarrheal illness related among children under five in low-income villages in Faisalabad District, Pakistan?
ApproachWe enrolled 100 children, tested household drinking water for E. coli and total coliforms, interviewed caregivers, and reviewed health-center records for recent diarrheal episodes.
FindingThe study reported higher diarrhea prevalence among children drinking contaminated water. Because the design was observational, the result is an association rather than proof that the measured exposure caused each episode.

Comparative study of conventional and sorption-enhanced reforming models for hydrogen production

Co-author · Process modeling · Fuel · 2021

QuestionHow do conventional and sorption-enhanced steam-methane and autothermal reforming compare on methane conversion and hydrogen purity?
ApproachWe built and validated one-dimensional reactor models for four reforming pathways and compared their performance across temperature and pressure ranges.
FindingAt the selected operating point, the sorption-enhanced routes increased modeled methane conversion from 32% and 51% to 66% and 76%, while hydrogen purity increased from 55% to 87% and 92%.
