Jill Marie SteinbachBioengineering

My background, comprised of both Materials Science Engineering and Biomedical Engineering, provides me with the versatile experience to design and develop drug/gene delivery vehicles and biomaterials for physiologically difficult-to-deliver-to microenvironments. My long-term goals are to create drug and gene delivery vehicles that provide more efficacious prophylactics/treatments for sexually transmitted infections (STIs), including acute and chronic (latent) infections. In addition to developing better vehicles that specifically target viruses and host cells, significant advancements can be made to rationally design delivery platforms targeted to the unique microenvironments where infection, latency, and reactivation occur. Gene and drug delivery vehicles, especially those suitable for delivery to the peripheral and central nervous systems (PNS/CNS) ‒ sites of HSV latency ‒ are still in the nascent stages of development. Similarly, the development of next-generation microbicides, offers burgeoning opportunities to create biomaterial combinations that can adapt to the acidic and mucosal intravaginal environment to provide multipurpose (contraceptive and viral) prevention modalities. Beyond these core research goals, I am excited to pursue collaborations involving the development of novel delivery systems for a wide range of pathologies including: cancer progression, virus infection, and delivery to generally challenging physiological environments.

Eric BersonChemical EngineeringResearch focuses on the development and/or improvement of bio-processes where existing techniques are limited due to complexities with the working media such as multi-phases, high-solids content, and complex flow fields. Example applications include: conversion of biomass to fuels and chemicals, characterization of fluid forces in complex (such as orbiting and sinusoidal) flow fields, correlations of fluid forces to biological responses, and characterization and kinetic modeling of enzymatic and anaerobic processes.  Integrating computational fluid dynamics with experimental work provides an excellent tool for overcoming limitations when experimental observations or measurements are difficult or impractical, such as in the analysis of biological systems and reactors for biomedical and energy applications. By experimentally validating certain conditions, the models can be extrapolated to more complex scenarios with a high degree of confidence. This provides a means for finding creative solutions to problems  that otherwise could not be solved with the same level of detail and accuracy or could not be solved at all.

Thomas L. StarrChemical EngineeringDr. Starr has conducted research in additive manufacturing and 3D printing technology for nearly 20 years. Over the past several years Dr. Starr’s investigation of mechanical performance of metal alloys fabricated by LS has produced some of the only openly-available data on fatigue performance of these materials. His prior work includes evaluation of stereolithography (SLA) tooling for ceramic injection molding, use of powder delivery laser deposition (LD) for combinatorial alloy development, and powder bed laser sintering (LS) for additive manufacturing of plastic and metal parts.  His research aims to create better understanding of the laser sintering process for both metals and polymers and how process parameters affect mechanical performance.  His work with polymer LS led to a new correlation among process parameters that better relates to mechanical performance.  This “energy-melt-ratio” is uniquely suited to investigation of new and higher temperature polymers.

    Arthur C. ParolaCivil & Environmental Engineering

    As the director of the UofL Stream Institute, Dr. Parola has led the restoration of more than 23,622 m of stream channels and the creation or restoration of hundreds of acres of associated wetlands. Characteristics of the restoration sites have varied widely: contributing drainage areas of less than 1 km2 to approximately 306 km2; channel substrates of clay, silt, sand, gravel, and cobble in floodplains composed of materials ranging from clay to loess to laminated layers of silt over gravel; high-gradient headwater valleys to extremely low-gradient coastal plain bottomlands; and highly urbanized to primarily agricultural to heavily forested watersheds.

    Dr. Parola and the team of graduate and undergraduate students, staff, and faculty who make up the institute have pioneered numerous new methods for assess¬ment, design, construction, and monitoring of stream and wetland restoration projects. Their design methods, developed in collaboration with construction contractors, integrate concepts and techniques from engineering, geomorphology, and ecology. This multi¬disciplinary approach has been essential to the restoration of self-sustaining stream-and-wetland complexes. One of the fundamental components of this design approach has been the use of two-dimensional numerical modeling to design the valley topography and the planform characteristics of channels. A second fundamental component of this approach has been to restore both ground¬water and surface water processes in the floodplain and channel. By raising the water table, the Stream Institute has been able to restore hydrologic con¬ditions that support extensive riparian wetlands. In some sites, this has required modifying groundwater flow with the construction of underground dams, a technique developed in collaboration with Tom Biebighauser of the US Forest Service. Through similar collaboration with other biologists, the Stream Institute has been able to incorporate hydrologic and morphological design components that support habitat requirements of resident aquatic organisms, including threatened and endangered species.

    Another significant component of several Stream Institute restorations has been consideration of neighboring built environments or farmlands. Riparian landowners have frequently suffered property damage and loss as a result of historic and recent channel manipulation and land use practices. In consultation with landowners and other watershed stakeholders, Dr. Parola has developed designs that have enhanced, rehabilitated, and/or re-created stream and wetland systems while also augmenting pasture, reducing flood levels in residential areas and farmlands, or otherwise improving the utility and condition of nearby property. Thus, the restoration projects benefited not only the stream ecosystems but also the stakeholders who used nearby land and infrastructure.

    Thomas RockawayCivil & Environmental EngineeringIn Kentucky and throughout the United States the distribution and transportation infrastructure is growing older … but not gracefully. Gradual deterioration of roadways and bridges, water and sewer systems, and gas and electric distribution networks eventually produces critical failures and disruptions. Inspection, maintenance and repair of these massive systems is a challenge with important consequences for the public welfare. New technologies need to be identified, developed and demonstrated to allow cost-effective maintenance and repair of major infrastructure elements. The Center for Infrastructure Research serves as a focal point for research and development on aging infrastructure issues. The Center for Infrastructure Research is a strong partnership between UofL, utilities and industry formed to research, educate and solve urban infrastructure-related issues and problems.  The Center is a technical resource, knowledge center and educational provider for utilities, industry and the community.

    Stuart WilliamsMechanical EngineeringResearch within this lab is focused on investigating micro- and nano-scale fluid phenomena. At this scale there are a number of phenomena that dictate hydrodynamic behavior that would normally be negligible in the macro-scale domain including thermal, optical, electrical, and capillary forces. These forces are utilized to design and fabricate novel microfluidic devices capable of a variety of tasks; some examples include (i) hydrodynamic pumping without moving parts, (ii) droplet generation, (iii) particulate trapping and/or sorting, (iv) biological characterization, and (v) self-assembly. Microfluidic investigations are centered around Particle Image Velocimetry (PIV). This laboratory is well-versed in PIV and can obtain a picture of flow fields within micrometer-sized fluid channels. Our goal is to explore the fundamental physics associated with microfluidic hydrodynamics, electrokinetic mechanisms, and colloid-based phenomena and develop related applications involving enhanced engineered materials or point-of-care diagnostics.
