Strengthening the operations that keep people fed, housed, and healthy.
Assistant Professor of Operations Management at Rutgers School of Business Camden in New Jersey
About me
I am a logistician and data scientist, at Rutgers University Camden. I work on retail and frontline services, making key goods and services available and figuring out how those products help people. Before Rutgers, I worked in industry in operational and analytics roles, with UN postings including in Somalia plus analysis roles at a major public ambulance service and the largest nonprofit hospital in New York City.

Operations Research
These are write ups from recent partnerships and field studies.
Operations analysts and city planners should work together to solve urban problems — but, first, should learn from the challenges with collaborations that unfolded 50 years ago.

Capacity planners in ambulance services can get efficiency and likely effectiveness gains from designating one ambulance squad for 911 calls involving opioids and homelessness, a casual study indicates. Massachusetts drew on this in a helpful 2023 report about care delivery. This was the runner up to the INFORMS MSOM Society Award for Responsible Research.

Inventory managers in the agricultural sector in Senegal actually face quality risks more than any others including financial risks, based on a door-to-door survey of retailers in 35 cities in a region. This was supported by Community Jameel.

Manufacturing managers working in the Ugandan agriculture sector would lean toward under-producing stocks, based on an experimental lab exercise in Kampala. This was supported by the US Agency for International Development.

Urban Planning and Policy Research
These are articles from recent nationwide econometric studies or analyses of city and federal operations.
Housing planners should expect the most affordable rental stocks to jump 5% in price after floods, a causal national analysis shows.

Capacity planners in ambulance services should prepare for a jump in demand for care six days after citywide cases of COVID spike.

Housing planners appear to grow their low-income rental inventory after floods–and this happens mostly out of floodplains–according to a causal analysis of nationwide data.

Housing planners should expect inventory turnover in the form of evictions–especially in expensive areas–to spike after disasters, a causal analysis of nationwide panel data shows. This was covered by the Associated Press, Urban Institute, and the Connecticut Mirror.
Mark Brennan, Tanaya Srini, Justin Steil, Miho Mazereeuw, Larisa Ovalles. 2022. “A perfect storm? Disasters and evictions.” Housing Policy Debates.32 (1), 52-83.
Most housing planners at state agencies do not have specific rules about siting buildings for low-income renters away from floodplains. The National Low Income Housing Coalition wrote a helpful summary.

USAID supply planners can get timeliness and cost gains from modernizing how food is bagged in the American food aid supply chain, based on a large pilot procurement. A major development news agency Devex covered this and it was supported by the US Agency for International Development.
