News and Announcements

  • AIChE Poster Awards

    In October, the RPS Lab attended the Annual AIChE Conference in San Diego, CA. At this conference, two undergraduate researchers – David Amirsadri and Colby Constantine – presented posters on their research projects, and both students received poster awards for their presentations. Congratulations!

    David Amirsadri

    Poster: Dynamics of Polymer-Grafted Nanoparticle Suspensions

    Award: 2nd Place Undergraduate Poster in Materials Engineering and Sciences Session.

    This project combines his research in our group with the research he performed at an REU over the summer with Dr. Kiril Streletzky at Cleveland State University and Dr. Michael Hore at Case Western Reserve University. His investigation characterizes the thickness of grafted polymer layers on anisotropic nanorods and their aggregation in thermally responsive solvents.

    Colby Constantine

    Poster: Characterizing Nanoparticle Dynamics in Biorelevant Materials to Predict Epithelial Transport Properties of Orally Administered Medications

    Award: 2nd Place Undergraduate Poster in Food, Pharmaceutical, and Biotechnology Session.

    This two-part investigation develops synthetic materials that mimic the hierarchical structure of mucosal layers in the body and identifies nanoparticle dynamics in these biomimetic systems.

  • Welcome New Students!

    The RPS Lab for Soft Matter Research is excited to welcome three new students into our group:

    Graduate Students:

    Sabirul Khan Priyo

    Sabirul joins us from Bangladesh University of Engineering and Technology where he completed his Bachelors in Chemical Engineering. He will be working to develop new polymer chemistries to promote bridge formation in colloidal suspensions.

    Sepehr Yari

    Sepehr joins us from Sharif University of Technology where he completed his Bachelors in Materials Science and Engineering. He will be working on a joint project with Dr. Daniel Roxbury (URI CHE) to investigate the intracellular dynamics of carbon nanotubes as a physical sensor of cellular health.

    Undergraduate students:

    Gabriel Stradtman

    Gabriel is a Junior working towards his Bachelors in Mechanical Engineering. He joins our team working with Elnaz Nikoumanesh to develop printability metrics for thixotropic yield stress fluids.

    Congratulations to both students for receiving these awards recognizing their hard work and contributions to soft matter and polymer physics!

  • RPS Lab Research Featured at AIChE
    Nanoparticle transport in biomimetic polymer-linked emulsions, AIChE Journal, 2024

    The American Institute of Chemical Engineers recently highlighted our research on the cover of AIChE Journal and in a feature in Chemical Engineering Processes magazine.

    Our work aims to understand how nanoparticles penetrate and transport through biological tissues so that we can better design and innovate drug delivery strategies. To accomplish this task, we developed a new class of biomimetic materials known as polymer-linked emulsions which replicate both the structure and mechanics of soft tissues. A team of graduate and undergraduate students – Daniel Keane, Colby Constantine, and Matthew Mellor – then conducted optical tracking measurements in these materials to demonstrate that we sufficiently replicate biologically relevant transport properties. Future work will establish correlations between the in vitro transport observed in polymer-linked emulsions and in vivo transport observed in animal models to (1) better understand the mechanisms underlying nanoparticle transport, and (2) predict performance of drug delivery vectors.

  • RPS Lab Receives an NSF CAREER Award

    The National Science Foundation recently awarded our lab a grant titled “Telechelic triblock copolymers as a platform to design functional colloidal gels.” With these funds, totaling $589,933, we aim to develop transformative advances in the design of soft materials – specifically colloidal gels – with applications ranging from biomimicry to energy storage and additive manufacturing.

    Congratulations to all members of our research group for this prestigious award! New science awaits!

  • Undergraduate Colby Constantine Receives a (URI)^2 Grant
    Colby Constantine, CHE ’25

    Colby Constantine, CHE Class of 2025, has received a URI Undergraduate Research and Innovation (URI)2 grant totaling $1,000 for his project titled “Characterizing Nanoparticle Dynamics in Biorelevant Materials to Predict Epithelial Transport Properties of Orally Administered Medications.” This independent research project looks to extend our recent work on nanoparticle dynamics to predict penetration of orally administered medications across epithelial layers. The project is expected to start in Spring 2024 and conclude after an academic year. Congratulations, Colby!

  • Matthew Mellor Selected as a Future Leader in Chemical Engineering
