Project Description This project aims to study the gaps that arise in understanding and supporting self-regulated learning in the newly emerging online learning space, as demonstrated by the varied behaviors of different populations of students. In particular, we will address questions of how learning management system traces indicate successful self-regulated...

Project Description Wastewater-based epidemiology is a fast-evolving field with direct application and benefit in the management of pandemics. A key distinction of this approach is the ability to monitor entire communities or neighborhoods. However, when getting closer to structures, a separate question arises: are we performing fecal or wastewater sampling?...

Project Description Somebody once said, "What a fool can do for a dollar, an engineer can do for a nickel". Thinking about costs as an engineering constraint brings new life to old ideas. This is what makes the difference between an idea influencing a hundred people or a billion! With...

Project Description Transmitters used for radio frequency (RF) communications systems (cell phones, wifi, etc) need to be made linear so they don't introduce distortion into the data signal. Normally, this is done with digital signal processing techniques to "pre-distort" a signal as a way to correct for the nonlinearity of...

Project Description Ultrasound imaging is an important tool for medical diagnostics, but we must work to develop imaging sequences that can image faster and with greater clarity to address a wider range of patients and clinical tasks. We have developed a method that involves transmitting from each element on an...

Project Description The Vance Lab at the University of Colorado Boulder specializes in indoor and outdoor air quality investigations, with a special focus on aerosols or particulate matter (PM). PM can range from a few nanometers to micrometers in size and can be generated from a variety of sources, from...

Project Description The conventional technology for recovery of valuable hydrophobic particles from aqueous suspension is froth flotation, where air bubbles rising through the suspension capture the particles and are collected in a froth layer at the top. However, froth flotation is not effective for particles smaller than about 10 microns...

Project Description Working on a project funded through the NSF designing and prototyping a robotic arm that is able to attach to a research drone used to collect samples from ice floes in the Arctic that are too soft for researchers to walk on. This person will work with a...

Project Description The carbon cycle controls all life on earth, yet we still lack a complete understanding of the largest reactive organic carbon pool on the planet, dissolved organic matter (DOM). Important ecosystem functions rely and depend on DOM as it controls nutrient availability, light attenuation, microbial respiration, and contaminant...

Project Description We are looking for a student to aid in understanding the career pathways of global engineering students and building a research base on the education of these students. This study hopes to unearth some of the structures in global engineering and development that are both preventing and aiding...
