The Human Factors Engineering (HFE) Laboratory is a team-based teaching and research laboratory for undergraduate and graduate students.  The laboratory focuses on cognitive, ergonomic, and environmental aspects of human factors, and their influence on product design, productivity and quality.  The lab has a wide array of hardware and software.

The Laboratory for Advanced Materials at Pittsburgh (LAMP) under the direction of Professor Paul W. Leu, focuses on designing and understanding advanced materials by computational modeling and experimental research. Simulations and experiments are used in a synergistic manner to study the mechanical and electronic properties of nanomaterials and surfaces for various applications. Take a virtual tour of our lab, which resides right across the hallway from the Pitt Nanoscale Fabrication and Characterization Facility

The goal of LAMP is to design better material systems through a combined modeling and experimental approach. Much in the same way that finite element modeling is now foundational in mechanical engineering design, multiscale and device modeling will become increasingly important in the prediction and understanding of nanomaterial and surface properties. In addition, these techniques can be used as a design tool for evaluating and optimizing various design metrics. Current areas of interest include:

  • Ab initio modeling of nanomaterials and surfaces 
  • Combining physical simulations with optimization methods 
  • Nanomaterial manufacturing and characterization
  • Solar cells

 

This research group, headed by Dr. Youngjae Chun, is a collaboration between the Departments of Industrial Engineering and Bioengineering. Current research interests include artificial biomaterials, composites, endovascular devices, diagnostic vascular implants, and micro-bio-systems, as well as fundamental device-associated biocompatibility and development of experimental techniques. Specifically, the work in the area of:

  • Designing and Manufacturing Medical Devices for Treating Vascular Diseases
  • Development of Artificial Biomaterials and Bio-hybrid Composites
  • Micro Fabrication and Nanoscale Characterization
  • Studies on Hemocompatible Surface Modification of Biomaterials
  • In-vitro tests: Device functionality, Hemocompatibility, Inflammatory Response
  • Investigation on Hemodynamics using MEMS transducer arrays
  • In-vivo Animal Testing and Post-mortem Examination

 

The NanoProduct Lab, also known as the Bedewy Research Group, at the University of Pittsburgh was established by and is currently led by Dr. Mostafa Bedewy (Assistant Professor of Industrial Engineering).

The group focuses on fundamental experimental research at the interface between nanoscience, biotechnology, and manufacturing engineering. Researchers in the NanoProduct Lab make basic scientific discoveries and applied technological developments in the broad area of advanced manufacturing at multiple length scales, aiming at creating novel solutions that impact major societal challenges in areas related to energy, healthcare, and the environment.

We are located in Benedum Hall in the Swanson School of Engineering (SSoE). We are part of the manufacturing group in the Department of Industrial Engineering (IE), and we are also affiliated with the Center for Energy, and the Petersen Institute of NanoScience and Engineering (PINSE).

Research Interests

  • Science and technology of nanomanufacturing process development
  • Nondestructive materials characterization and metrology
  • Precision design and fabrication of scientific instruments, manufacturing machines, and medical devices
  • Synthesis and self-organization of nanofilaments, such as carbon nanotubes, and their composites

The goal of the Operations Research and Analytics in Healthcare (ORAH) Lab is twofold: (1) to identify significant challenges and pressing issues in healthcare operations, health policy, and medical decision making, and (2) to develop innovative Operations Research and Analytics methods to provide quantitative, evidence-based solutions that address these challenges. Operations, decisions and policymaking in healthcare involve complex issues such as high degrees of uncertainty, difficult trade-offs, and conflicting objectives that dynamically evolve over time. Researchers in the ORAH Lab focus on modeling and analysis of such complex healthcare problems by utilizing an array of advanced quantitative methods such as stochastic modeling, mathematical optimization, simulation and machine learning. The ORAH Lab emphasizes both the development of novel and creative methodology and interdisciplinary research via active collaboration with health researchers and practitioners. These methodologies and collaborations generate rigorous and viable solutions to inform medical decisions, operations strategies and public health policy in broad healthcare settings.

Research projects in the ORAH Lab are primary funded by the National Science Foundation, the National Institutes of Health, and other federal agencies. Past and ongoing projects include:

  • Medical decision making applications in organ transplantation, cardiac device care and therapy sequencing in chronic disease management;
  • Healthcare operations applications in vaccine administration, donor milk processing, COVID-induced drug supply shortages, biomanufacturing, and cancer therapy design and delivery;
  • Health policy applications in organ allocation, incentive design, and paid sick days legislation.

In an ongoing study, we are exploring the design and characterization of multifunctional surfaces and bulk metallic-forms that are composed of nano-scale grain structures. In another study, we are developing new in situ methodologies for examining the mechanics of deformation and microstructure evolution in micro-scale deformation processing. Recently, we have begun a new study aimed at developing scalable routes for manufacturing hierarchical nano-scale topographies in polymeric materials, as well as the development of novel photomechanical machines that are actuated, controlled and assembled exclusively with light. 

Applications of our research include the development of high performance structural and functional materials, innovative biomedical components with tunable functional and mechanical properties, as well as the utilization of novel biomimetic hierarchical nano-architectures in engineering applications.

 

The Sociotechnical Systems Research lab is led by Prof. Amin Rahimian,  and the focus is on questions that help society navigate the age of data. On the one hand, the landscape for scientific research is itself changing: the combined force of high-end data analytics and high-performance computing opens new ways for scientific discovery; more and more data from various sources and in novel forms are available to facilitate scientific inquiries. On the other hand, to overcome the trust barriers and embrace the increasing role of data and algorithms in our lives, we need a scientific understanding of the algorithmic, data-driven and platform-based economies that algorithms enable. The lab’s research into large-scale, sociotechnical systems is aimed at helping society in this transition by deepening an understanding of the emerging, data-enabled infrastructure within its societal context. 

The primary mission of the Stochastic Modeling, Analysis and Control (SMAC) Lab is to address challenges encountered in the mathematical modeling, analysis, and control of engineering, service, and other systems that have inherently stochastic elements. Examples of such systems include energy, production, telecommunications, inventory, and healthcare. Research in the lab emphasizes analytical and computer-based modeling of such systems and their optimization by exploiting applied probability, stochastic processes, and stochastic optimal control techniques. This collaborative laboratory’s aim is to generate, analyze and provide viable solutions to complex, often sequential, decision-making problems in uncertain environments. The SMAC Lab is primarily funded through grants from the National Science Foundation, the U.S. Department of Defense, and other governmental agencies.  Current research thrusts in the laboratory include:

  • the modeling, analysis, and optimization of energy storage systems;
  • mission abort decision making;
  • degradation-based reliability modeling and evaluation;
  • data-driven, adaptive maintenance planning models;
  • spare parts inventory modeling and control;
  • healthcare applications;
  • sequential analysis and quickest change detection in science and engineering.
