Professor in the Department of Mechanical Engineering and Materials Science
Professor Needham has been at Duke since 1987 and over the years has developed many collaborative and scholarly relationships across the campus and Medical School. He holds Faculty and membership appointments as: Associate Professor of Biomedical Engineering; Center for Bioinspired Materials and Material Systems; Center for Biomolecular and Tissue Engineering; Duke Comprehensive Cancer Center; and the Duke Cancer Institute. Internationally, he holds a joint appointment as Professor of Translational Therapeutics in the School of Pharmacy, at the University of Nottingham, UK. He also collaborates with preclinical researchers at the Erasmus University Medical Center, in Rotterdam, NL.
For the past 35 years Needham's Lab has developed and used a platform technology of micropipette manipulation to manipulate single and pairs of micro bubbles, droplets and particles in order to assess their behavior in well-defined fluids and solution conditions. Recently his research and development has focused on nucleation, growth and stability of nanoparticles. Applications of these fundamental particle and interfacial studies have primarily focused on advanced drug delivery treatments for cancer and now COVID19 with a nasal and throat spray prophylactic and early treatment regimen.

Needham’s research and development is nothing if it is not collaborative.
- Anti-cancer drug delivery inspired by how cancer's survive and spread due to their consumption of Lipoprotein particles from the blood-stream (LDLs and VLDLs) hence his approach:
- Make the drug look like the cancer's food" Converts low solubility drugs ("bricks") into even lower solubility "Rocks" that can be made into nanoparticles of pure drug made =by the solvent exchange process, hence his "Bricks to Rocks technology (B2RT)
- Explored the pH dependence of Niclosamide solubility, dissolution, and morphology and created a potentially universal mucin-penetrating nasal and throat sprays for COVID19, its viral variants and other viral infections.
- Single micro- and nano-particle science and engineering utilizing a micropipette technique for single particle micromanipulation.
For the past 35 years Needham's Lab has developed and used a platform technology of micropipette manipulation to manipulate single and pairs of micro particles in order to assess their behavior in well-defined fluids and solution conditions. With these techniques, he brings a wealth of expertise in colloid and interfacial science and engineering evaluating all 3 states of matter and their 5 interfaces, at the microscale, as micro-bubbles, -drops and -particles. Results of these kinds of studies have impacted: bubble technology for ultrasound; Droplet Interface Bilayers (DIBs) in collaboration with the Hagan Bayley lab at the University of Oxford UK; as well as the microglassification of proteins and peptides for storage, transport and use. This technology is now being developed by his ex-graduate student now CEO and Founder of Lindy Biosciences, Deborah Bitterfield PhD. Other industrial collaborations arising from the micropipet studies include with Gary Fujii, PhD, CEO and Founder of Molecular Express Inc in Los Angeles, California on a variety of products including a new lung surfactant for respiratory distress syndromes
Applications of these fundamental particle and interfacial studies have primarily focused on advanced drug delivery treatments for cancer. Of note over the past 20 years has been his invention and development of the Low-Temperature-Sensitive Liposome system for treatment of local cancers that can be warmed by mild hyperthermia. This 1996 invention was pre-clinically and clinically developed with collaborators in the Duke Medical Center, specifically with Dr. Mark Dewhirst PhD DVM (now retired) and his then Hyperthermia Program in Radiation Oncology and the Duke Cancer Institute and licensed to Celsion Corporation.
Recently his research and development has focused on nanoparticles, again for anti-cancer applications. Recognizing that cancers are known to “feed” on Low Density Lipoprotein (LDL) particles (--sub microscopic nanoparticles composed of fat and protein) from the blood stream, his new strategy is to “make the drug look like the cancer’s food”. The new technology turns the low solubility “bricks” of the pharmaceutical industry, that are very difficult to administer in effective doses by oral tablets, and turns them into much less soluble “rocks” so that they can be made into the LDL-sized nanoparticles for intravenous delivery. This work is in close collaboration with his colleague, Dave Gooden PhD, Director of the Duke Small Molecule Synthesis Facility; hence their “Bricks-to-Rocks Technology (B2RT). Here, in collaboration, with Will Eward DVM, MD Dept of Surgical Oncology and Ivan Spasojevic, PhD, Director of the PK/PD core, they have pioneered testing this new kind of anti-cancer drug nanoparticle. It has already shown positive results in a lung-metastatic mouse model of Osteosarcoma, as well as in a recent feasibility trial in canine patients with Steve Suter VMD, MS, PhD, DACVIM and colleagues at the NC State Veterinary School.
Finally, over the past year, responding to the COVID19 pandemic, Needham has developed 11 provisional patent applications and one in particular is now forming the basis for a new nasal and throat spray that is intended for use as a Prophylactic-Preventative and in early treatment of COVID19. This work is being carried out in a new collaboration with Christina BArkauskas, Assistant Professor in Pulmonary, Allergy and Critical Care Medicine, along with Dr Patty Lee and her lab. Together they are actively pursuing Investigational New Drug (IND) studies required to advance the new spray to testing in patients.
