Core Research Areas

The Bioengineering department at UCLA focuses its research and curriculum on five key areas:

Molecular, Cellular, and Tissue Engineering (MCTT)

This field delves into therapeutic development across all biological scales, from molecules and cells to tissues. Researchers investigate the properties of tissues like bone and muscle, explore the use of biomaterials, and study the complex interactions between implants and the body. The emphasis is on understanding the fundamental basis for diagnosis, disease treatment, and the redesign of molecular, cellular, and tissue functions. Quantitative experiments, along with quantitative and integrative modeling approaches, are employed to gain spatial and temporal information at various levels.

The Weintraub Center, aligned with this area, focuses on developing methods to improve the quality of life for people who have experienced loss of oral or facial structures. Interdisciplinary research collaborations translate molecular, cellular, and organ characteristics of tissue damage and repair processes into reconstructive approaches for child and adult patients.

Biomedical Devices and Bioinstrumentation (BMI)

This area focuses on training bioengineers in the application and development of instrumentation used in medicine and biotechnology. Examples include lasers in surgery and diagnostics, microelectrical machines for surgery, sensors for detecting and monitoring disease, microfluidic systems for cell-based diagnostics, and controlled drug delivery devices. The principles underlying each instrument and specific clinical or biological needs are emphasized.

Biomedical Imaging

UCLA has a strong presence in biomedical imaging, which encompasses the development and application of imaging technologies for visualizing biological processes and diagnosing diseases. The Crump Institute for Molecular Imaging (CIMI) plays a central role in this area, bringing together scientists to develop state-of-the-art imaging technology and molecular imaging assays for studying biological systems. The Department of Radiological Science’s Magnetic Resonance Research Labs (MRRL) also contributes significantly to this field, operating the Magnetic Resonance Research Center for advanced imaging research.

Biomedical Data Sciences

This area focuses on the development and application of computational and statistical methods to analyze large and complex biomedical datasets. Research in this area aims to extract meaningful information from data to improve disease diagnosis, treatment, and prevention. The biomedical signal and image processing (BSIP) field prepares students for careers in the acquisition and analysis of biomedical signals, enabling them to apply quantitative methods to extract meaningful information for both clinical and research applications.

Neural Engineering (NE)

The neuroengineering (NE) field is designed to enable students with a background in biological sciences to develop and execute projects that make use of state-of-the-art technology, including microelectromechanical systems (MEMS), signal processing, and photonics. Students with a background in engineering develop and execute projects that address problems that have a neuroscientific base, including locomotion and pattern generation, central control of movement, and the processing of sensory information. Trainees develop the capacity for multidisciplinary teamwork, in intellectually and socially diverse settings, that is necessary for new scientific insights and dramatic technological progress. Students follow a curriculum designed to encourage cross-fertilization of neuroscience and engineering.

The Brain Research Institute (BRI): The BRI's goal is for UCLA to become the preeminent center of excellence for neuroscience research and education and for the “translation” of research into clinical and technological applications. Its efforts focus on learning, memory, and plasticity; neural repair; neuroengineering; and neurogenetics.
The Center for Advanced Surgical and Interventional Technology (CASIT): This UCLA-designated research facility provides a platform for developing and testing new surgical and interventional technologies.
The Center for Embedded Networked Sensing (CENS): As a NSF Science & Technology Center, CENS is developing Embedded Networked Sensing Systems and applying this revolutionary technology to critical scientific and social applications.
Biosystems Science and Engineering (BSSE): Graduate study in biosystems science and engineering (BSSE) emphasizes the systems aspects of living processes, as well as their component parts. It is intended for science and engineering students interested in understanding biocontrol, regulation, communication, and measurement or visualization of biomedical systems (of aggregate parts - whole systems), for basic or clinical applications. Dynamic systems engineering, mathematical, statistical, and multiscale computational modeling and optimization methods - applicable at all biosystems levels - form the theoretical underpinnings of the field. Typical research areas include molecular and cellular systems physiology, organ systems physiology, and medical, pharmacological, and pharmacogenomic systems studies, neurosystems, imaging and remote sensing systems, robotics, learning and knowledge-based systems, visualization, and virtual clinical environments.
Medical Imaging Informatics (MII): Medical imaging informatics (MII) is the rapidly evolving field that combines biomedical informatics and imaging, developing and adapting core methods in informatics to improve the usage and application of imaging in healthcare. Imaging informatics research concerns itself with the full spectrum of low-level concepts (e.g., image standardization and processing, image feature extraction) to higher-level abstractions (e.g., associating semantic meaning to a region in an image, visualization and fusion of images with other biomedical data) and ultimately, applications and the derivation of new knowledge from imaging.

Undergraduate Research Opportunities

Research is a crucial component of undergraduate education in Bioengineering at UCLA. Undergraduates have the opportunity to work in UCLA faculty laboratories alongside graduate students and post-doctoral scholars, tackling open-ended problems at the forefront of bioengineering. These research projects allow students to explore various fields within bioengineering, preparing them for future careers in industry, medicine, and research. Students can also receive course credit for their research experiences. The Undergraduate Research Center - Sciences provides support for undergraduates and faculty in the sciences, engineering, and mathematics. Additionally, the Undergraduate Internship Program (UIP) assists Samueli Engineering students by providing resources, information, and opportunities.

Nanotechnology in Bioengineering

Nanotechnology plays an increasingly important role in bioengineering research at UCLA. Researchers are creating nanomaterials for targeted drug and gene delivery, more efficient production of cells for use as therapies, and better models of human disease. The application of nanotechnology in medicine recreates the natural scale of biological phenomena, enabling more precise and less invasive approaches for preventing, diagnosing and treating disease.

Curriculum Structure

To provide students with a strong foundation in bioengineering, the curriculum is structured around core courses, field-specific courses, and elective courses.
