VectorPAL: an Integrated Entomological Decision Support System for Malaria Control

With VectorCam, frontline health workers can now identify mosquito species in the field without lab support, significantly improving the timeliness and quality of vector data. Our team is investigating the next step: how to turn that data into action. VectorPAL is a decision-support concept that synthesizes entomological, environmental, and behavioral inputs to recommend feasible, community-level interventions. Through stakeholder interviews, fieldwork in Uganda, and expert consultation, we are evaluating how such a tool could support district officers and village health teams in selecting strategies—like larval source management or ITN behavior reinforcement—based on real-time conditions. This work focuses on closing the loop between surveillance and response, answering the “so what?” question that arises once high-quality data is available.

CMOS Imager

This work presents the design, simulation, and layout of a CMOS active pixel sensor (APS) employing a three-transistor (3T) architecture with integrated column-parallel readout. Each pixel consists of a reset switch, source-follower amplifier, and row-select device, interfacing with a photodiode that generates a photocurrent proportional to incident illumination. A current-mode column readout circuit enables robust signal acquisition and biasing. Pixel functionality is validated through transient simulations utilizing modeled photocurrents and bias voltages. Row and column scanning are achieved using custom C²MOS shift registers to facilitate sequential raster readout. A 4×4 pixel array is implemented and laid out within a 2.5 mm × 2.5 mm die area, achieving full DRC and LVS compliance. The design demonstrates high fill factor, low-power operation, and scalability, providing a foundation for future monolithic CMOS imaging systems.

It is wonderful to watch students from different departments work together to support better engineering design opportunities at Hopkins.

To identify what can satisfy students from every engineering perspective has been both challenging and rewarding, as I’ve learned leading the multidisciplinary student advisory board for the Design Center.

The First Year Seminar Design CornerStone helped me get exposed to a wide range of engineering disciplines and introduced me to all the makerspace and departments opportunities at Hopkins!

I am excited to take advantage of all the resources available to strengthen my engineering skills.
