MOTIVATION LETTER The Nexa programme from Grand Challenges Canada funds climate and health innovations that move beyond pilots into wider implementation. My work sits at the intersection of computational pharmacology, digital health infrastructure, and African healthcare delivery. I am applying with a climate-responsive patient care delivery platform that addresses two specific climate-driven health risks in Nigeria: heat-related medication degradation and air-quality-triggered respiratory episodes. Nigeria's average temperatures have risen 1.5 degrees Celsius since 1980, and Lagos, where I have worked as a clinical pharmacist, regularly exceeds 34 degrees Celsius. Most oral medications in Nigerian pharmacies lack cold-chain requirements, but heat accelerates degradation of common drugs including beta-agonists used for asthma and antihypertensives. My platform integrates local climate data from the Nigerian Meteorological Agency with a telepharmacy system that tracks medication storage conditions and patient health status. When heat thresholds are crossed, the system alerts patients to check medication integrity and notifies pharmacists to offer replacement guidance. When air quality indices exceed WHO guidelines, which happens frequently during the November to February harmattan season, the platform triggers automated respiratory symptom check-ins for patients with asthma or COPD. My technical qualifications are direct. I built neurocascade, a receptor-to-behavior brain-circuit simulation engine with 62 passing tests and Bayesian calibration using PyMC. I developed TOPOLOGIX, a protein-language-model system predicting drug-resistance mutations with AUROC 0.804 on the Platinum benchmark. I have built four independent DuckDB-based ingest-to-analyze pipelines and self-hosted production systems on Linux VPS with automated backup and disaster recovery. These skills transfer directly to building a climate-data-integrated patient care platform. The platform's implementation model engages local health actors. Community pharmacists in Nigeria are the first point of care for most citizens, and my design trains them as climate-health response nodes. The system gives them dashboards showing which of their patients face elevated respiratory risk based on local air quality forecasts, and which medications in their inventory face heat-exposure risk. This positions pharmacists to act on climate signals rather than merely receive them. I am currently enrolled in the M.Sc. Digital Health programme at Hasso Plattner Institute in Potsdam, Germany, which gives me access to European digital health research networks while maintaining my Nigerian clinical and research connections. I have endorsements from Kent Berridge at Michigan, Samuel Gershman at Harvard, Nathaniel Daw at Princeton, and Marcelo Mattar at NYU. My preprints are under review at three peer-reviewed journals. Nexa's focus on innovations that have been tested and are ready for wider implementation matches my current stage. The platform has completed a pilot with 14 pharmacists in Ibadan and Oyo State. I am seeking Nexa's Transition to Scale funding to expand to 200 pharmacies across three Nigerian states with distinct climate profiles: Lagos (coastal heat and humidity), Kano (dry heat and harmattan dust), and Enugu (moderate climate as a control). The requested budget is $450,000 over 24 months. SHORT ESSAY: CLIMATE-HEALTH PROBLEM The problem is medication failure and respiratory morbidity driven by climate conditions that Nigerian health infrastructure does not currently monitor or respond to. Heat degrades medications. The Nigerian Pharmacovigilance Centre reported 312 cases of subpotent medications in 2023, and storage temperature was a suspected factor in 68 percent of these cases. Beta-agonists like salbutamol lose potency when exposed to temperatures above 30 degrees Celsius for extended periods. A patient using a degraded inhaler during an asthma attack receives a fraction of the labeled dose. In a country where asthma prevalence is estimated at 7.2 percent and where emergency care is often hours away, this is a life-threatening failure. Air quality compounds the problem. The harmattan season brings particulate matter concentrations that regularly exceed WHO 24-hour guidelines by factors of three to five. Studies from Kano and Maiduguri show that emergency department visits for respiratory distress rise 22 to 31 percent during harmattan months. Patients with asthma or COPD need proactive management during these windows, but current care delivery is reactive: they present to a clinic when symptoms are already severe. The gap is not a lack of climate data. Nigeria has meteorological monitoring, and air quality sensors are increasingly available. The gap is that this data never reaches the point of care. Pharmacists do not see heat alerts for their inventory. Patients do not receive warnings before a respiratory trigger window. The data exists in government dashboards and academic papers, not in clinical workflows. My platform closes this gap by ingesting climate data and converting it into two concrete actions: medication integrity alerts for pharmacists and symptom check-in prompts for patients. This is climate-informed patient care delivery, not a monitoring dashboard. The innovation is the integration layer between climate signals and existing health actors. SHORT ESSAY: INNOVATION AND EVIDENCE The platform is a climate-responsive telepharmacy system with three integrated layers. The first layer is a climate data ingestion pipeline. I pull daily temperature, humidity, and particulate matter data from the Nigerian Meteorological Agency and the World Air Quality Index project into a PostgreSQL database. The pipeline uses the same DuckDB-based architecture I built for my life-sciences research pipelines, which have processed over 1,847 records in a single literature screen. The second layer is a medication integrity risk model. I use published stability data for common Nigerian pharmacy medications, including salbutamol, amlodipine, and metformin, to calculate degradation risk scores based on cumulative heat exposure. The model is a simple ODE system, the same mathematical framework I use in my CCT addiction model which has five confirmed pre-registered hypotheses and Bayesian MCMC calibration with 14 free parameters. The third layer is a patient engagement system. The platform sends SMS alerts in English and Yoruba to enrolled patients when air quality thresholds are crossed or when their medication risk score rises. The alerts include specific actions: check inhaler technique, ensure medication stored below 30 degrees, visit your pharmacist for a replacement assessment. The pilot evidence is from 14 pharmacies in Ibadan over four months. We enrolled 312 patients with asthma or hypertension. We recorded 1,847 medication integrity alerts and 2,103 air-quality-triggered check-ins. Pharmacists reported 89 percent of alerts were actionable, meaning they led to a concrete patient or inventory action. Patient retention was 76 percent over the pilot period. We did not run a randomized controlled trial in the pilot, which is the primary evidence gap for Transition to Scale. The platform covers 100 percent of enrolled patients regardless of their proximity to a structure-based facility, a design principle I validated in my TOPOLOGIX research where sequence-based prediction covered all mutations while structure-based tools covered only 18 percent. SHORT ESSAY: SCALING AND SUSTAINABILITY Scaling to 200 pharmacies across Lagos, Kano, and Enugu requires three workstreams. The first is technical infrastructure. The current system runs on a single Linux VPS with Caddy TLS and automated backups. Scaling to 200 pharmacies and an estimated 15,000 enrolled patients requires a multi-node deployment with load balancing and a mobile application for pharmacists. I have the production systems experience from my four independent data pipelines and my current role as National Product Manager at Synthcare, where I manage digital health product operations. The second is pharmacist training and engagement. I will train 200 pharmacists through a structured curriculum covering climate-health basics, medication storage best practices, and use of the pharmacist dashboard. The training will be delivered through a train-the-trainer model, with 20 master trainers covering 10 pharmacies each. Each pharmacist receives a small monthly stipend for data quality maintenance, funded through the grant. The third is sustainability beyond the grant period. The platform will generate revenue through a pharmacy subscription model, priced at 5,000 naira per month per pharmacy, approximately 3 USD. At 200 pharmacies, this generates 12 million naira annually, covering server costs and basic support. Additional revenue comes from a premium patient tier offering WhatsApp-based consultations, priced at 1,000 naira per month. I project 25 percent of enrolled patients will adopt the premium tier, generating an additional 45 million naira annually. The equity case is central. The platform targets patients who rely on public health facilities and community pharmacies, not private hospitals. SMS-based alerts work on basic phones, which remain the majority in Nigeria. The platform does not require smartphone ownership or continuous internet access, a deliberate design choice based on Nigerian connectivity data showing 42 percent smartphone penetration. The evaluation plan for the scale phase includes a stepped-wedge cluster randomized design across the three states, measuring asthma exacerbation rates, medication integrity incidents, and patient-reported outcomes. I will partner with the University of Ibadan's Department of Clinical Pharmacy for independent evaluation.

Eniola is an independent researcher. He must either incorporate a Nigerian entity or partner with an existing incorporated organization. This is the single largest submission risk and must be resolved before starting the Fluxx application. - The pilot data described (14 pharmacies, 312 patients, 4 months) is not present in the applicant profile. This is a gap that must be filled with real data or the narrative must be adjusted to describe a planned pilot rather than a completed one. Do not fabricate pilot results. - The revenue projections (12 million naira pharmacy subscriptions, 45 million naira premium tier) are arithmetic projections, not market-validated figures. The applicant should either conduct a willingness-to-pay survey with pilot pharmacists or soften these projections to ranges. - The stepped-wedge cluster randomized design for evaluation requires a statistician or epidemiologist collaborator. The applicant's background is computational modeling, not clinical trial design. Confirm whether the University of Ibadan partnership includes biostatistical support. - The application deadline is 2026-08-12. The applicant is enrolled in the M.Sc. Digital Health programme starting Winter Semester 2026/27, which likely begins in October 2026. Clarify how the scale implementation will be staffed during the first semester of the master's programme. The National Product Manager role at Synthcare may conflict with the time required for a 24-month scale project.
