Mark Howison

An experienced data scientist.

Originally trained as a computer scientist, my career has led to multidisciplinary partnerships with economists, doctors, and policy makers to solve challenges in human health and public policy. Currently, I am a Senior Applied Scientist at Amazon (all opinions here are my own) working on employee experience. I also serve on the board of Research Improving People's Lives, a tech-for-social-impact nonprofit that helps governments use data, science, and technology to equitably improve policy and lives. I received my M.S. in Computer Science from UC Berkeley.


Projects


Pandemic Unemployment Assistance

I led the rapid development and deployment of Rhode Island's emergency unemployment assistance system in response to the COVID-19 economic shutdown. My team launched this production system in just 10 days following the passage of the US CARES Act. It accepted over 450,000 applications for benefits during its operation, accommodating a surge of 10,000 applications in the first 12 hours following launch.


Connecting Workers to New Careers

Through partnerships with state governments across the country, I led the development of recommendation systems that help job seekers discover new careers. The underlying algorithm uses causal machine learning methods to identify career transitions that resulted in increased earnings and employment for previous job seekers, and measures of skill similarity derived from natural-language processing of millions of full-text job descriptions.


Monitoring COVID-19 Variants

I developed the bioinformatics pipeline used to monitor the emergence and prevalence of COVID-19 variants in Rhode Island. Regular reports from this system provided the Rhode Island Department of Health and Governor's Office with information to guide their public health response to COVID-19.


Predicting Opioid Dependence

As many as 80% of those suffering with an opioid use disorder had a legitimate opioid prescription from a doctor prior to their diagnosis. I helped develop a predictive model for the risk of developing a disorder if given an opioid prescription. We are partnering with policymakers to provide this information to doctors when weighing the risks and benefits of opioid therapy for new patients.


The Rhode to College

I served as the technnology director for Rhode2College, an innovative program announced on Sep 24, 2018 by Governor Gina Raimondo to help Rhode Island high school students succeed on their path to college.


Big Data for Policy Innovation

I led a data science team that integrated over 800 data sets from Rhode Island government agencies into an anonymized and secure database for delivering policy insights.


Disrupting HIV Transmission

The actual transmission network between HIV-infected individuals is unknown, but gene sequencing of new infections can reveal patterns of transmission. I served as the lead bioinformatician on an NIH-funded project to use these patterns to help public health officials disrupt HIV transmission.


Data Mining

Data in the real world is messy and not always ready for analysis. I have developed computer-vision methods to extract historical data on changes in industrial land use from printed directories, natural language processing methods to extract occupation and skills from job postings and resumes, and a comprehensive directory of FDA drug codes for understanding prescriptions in medical claims.


Measuring HIV Drug Resistance

Modern gene sequencing technologies can monitor HIV infections with high precision and have the potential to improve and personalize drug therapies for treating HIV. I have studied methods for measuring drug resistance in HIV-infected individuals and worked with an international group of HIV researchers to recommend future standards for clinical applications.


Technology for Research

I understand the technological needs of researchers and can translate them into IT solutions. I was the technical architect for a secure computing environment at Brown University that served over 150 researchers across 17 labs and centers in fields such as public policy, economics, public health, and biomedical informatics. I have also conducted performance studies on large computing clusters and developed methods for managing research software and tracking complex analyses of big data.
