FACILITIES

Overview:

The Biomedical Photonics Laboratories recently moved to a newly renovated state-of-the-art facility, formerly known as the W.M. Keck Free Electron Laser (FEL) Center. This facility is located across the Biomedical Engineering Department as well as other Science and Engineering buildings and within 300 yrds of the Vanderbilt Medical Center. After the FEL program was ended the laboratory facilities underwent a $1 million renovation (completed in August 2010) which resulted in over 5,000 square foot of state-of-the-art Biomedical Photonics Laboratory space. Set up in part as core labs and in part as thematic research labs, this new facility includes laboratories for clinical spectroscopy/diagnostics, Raman spectroscopy, optical imaging, Optical Coherence Tomography (OCT), neurophotonics, high power lasers as well as core support facilities that include bioluminescence imaging, spectrophotometry, image analysis/processing, microscopy, small animal surgery and fully equipped labs for cell / tissue culture, histology and an electronics / machine shop. Finally, the facilities include a state-of-the-art optics teaching lab to provide our undergraduate and graduate student with hands-on training in biomedical photonics. All laboratories are equipped with black-out curtains and each lab is partitioned into independent sections each with dedicated lighting and air handling systems.

Office Space:

Each faculty member has a faculty office (200 sq.ft) in the BME department. Cubicle space for Postdoctoral fellows and Graduate Students is available in the Department on the 8th and 9th floor of the Science & Engineering building immediately adjacent to the Biomedical Photonics Laboratories. Each person in the department has a personal computer linked to the VU network. Centralized data storage and backup facilities are provided and supported by a server in the BME department. Administrative support is available in the BME department. A large conference room (30+ people capacity) with state-of-the-art video conferencing and data sharing capabilities is available in the new Biomedical Photonics Center.

Animal:

Vanderbilt University is an AAALAC accredited institution. Extensive animal care facilities are available to the investigators. This includes animal housing and care as well as a transgenic core facility maintained in the Vanderbilt-Ingram Cancer Center. The Animal Care Facility at Vanderbilt University Medical Center has four full time veterinarians (two of whom are ACLAM Diplomates) who are on call 24 hours a day for assistance with veterinary problems. The Biomedical Photonics labs have in-house capabilities for surgeries on small animals including surgical tools, an operating microscope and two animal anesthesia systems (VetEquip).

The third floor of the Vanderbilt University Institute for Imaging Sciences (VUIIS) building houses various imaging systems operated by the Center for Small Animal Imaging (CSAI). Multimodal imaging capabilities include microPET, bioluminescence, microCT and several small animal MRI systems. Infrastructure and personnel for animal imaging support including surgery, anesthetics and animal handling are adjacent to the CSAI suite. In addition, wet laboratories for chemistry and cell culture laboratories are also located on this level. The CSAI is fully staffed with support personnel.

Clinical:

The Vanderbilt Medical Center is approximately 300 yards away from the Biomedical Photonics Laboratories. The clinical operating room is approximately 400 yards away and is easily accessible with a cart containing the systems. The Vanderbilt-Ingram Cancer Center and the Monroe-Carell Childrens’s Hospital are a little further at 500 yards. A state of the art clinical facility housing several clinics such as the Vanderbilt Women Center, Dermatology clinic etc.is located 10 miles away with dedicated space for research studies.

Computer:

Every person in the Biophotonics Insititute has his or her own computer. In addition, there are PC based data acquisition systems available. Dedicated computers for instrument control (through LabVIEW), data collection and data analysis. There are several computers (PCs and a Macintosh) available in the Simulation and Computation modeling lab with various becessary software such as Matlab and Zeemax. Simulation for optical and thermal modeling is also accessible through these systems.. Access is also available to high computing clusters (ACCRE), university servers and UNIX machines.

Machine Shop:

A large, competent electronics and machine shop is available for use with prior approval. This shop is equipped with machining tools such as micro drill press. Electronic and optical components are also available here.
