A Guggenheim Fellow, Dr. Caruthers completed the Ph.D. at Northwestern University and post-doctoral studies at MIT.
Professor Caruthers interests include nucleic acids chemistry and biochemistry. Approximately 40 years ago, the methodologies for chemically synthesizing DNA/RNA were developed in his laboratory and incorporated into instruments for synthesizing DNA/RNA as used by biochemists, biologists, and molecular biologists. These methods remain the procedures of choice for preparing synthetic DNA and RNA. More recently his laboratory has developed methods for the synthesis of DNA/RNA on chips. His laboratory has also pioneered the synthesis of many new nucleic acid analogs that have found applications in the nucleic acid diagnostic and therapeutic areas.
He is the recipient of several academic and research awards including The National Academy of Sciences Award in the Chemical Sciences, The Prelog Medal, The Economists Award in Biotechnology, and The US National Medal of Science.

Raising the bar on analytical performance and consistency by overcoming non-specific adsorption challenges
Oligonucleotides and nucleic acids are polar and negatively charged molecules with propensity to adsorb to metal surfaces. The undesirable metal interaction often confounds the chromatographic results and make it difficult to achieve a consistent analytical performance. The use of a high performance organic/inorganic surface technology has been shown to greatly minimize the metal surface adsorption and has proven to improve consistency of analytical results within a liquid chromatography system and across systems. The instrument surface modification enables greater nucleic acid recovery and improves mass spectrometry limits of detection. The improved analytical performance on modified chromatography systems is achieved without a need for system conditioning routinely performed today to mitigate the unwanted sample adsorption on metal hardware.

Drug Delivery Topic-
Targeted delivery of RNA using viral biology
- Oligo based therapeutics can achieve better efficacy if targeted, and therefore several biological and chemical approaches are being tested. Can oligo delivery go beyond the usual suspects, such as the liver?
- Immunogenicity continues to hinder targeted delivery using viral based approaches. Can synthetic biology help overcome this issue?
- Are there tissues/cell types that can benefit from targeted delivery of oligos and why?

Research Scientist
SRI International
Priyanka Shukla, Ph.D., is a Research Scientist in Macromolecular Biosciences at SRI International. Challenges to siRNA delivery have made the development of safe and effective delivery systems paramount in siRNA research. To overcome the barriers to siRNA delivery, a systematic cell-targeting system is needed to deliver this bioactive cargo to a specific cell type and to precise locations within that cell. With this goal, she has used SRI’s Novel FOX Three TM, Molecular Guidance Systems (MGSs), to successfully deliver gene-targeted siRNA bioconjugates into specific cell types. This allows for precision delivery of siRNA that remains fully functional in knocking down the gene expression.
Dr. Shukla obtained her Ph.D. in Translational Biomedicine at the University of Verona, Italy. She continued her training at Memorial Sloan Kettering Cancer Center in New York, where she was a Research Fellow in Molecular Pharmacology. She then ventured to the University of Virginia where she was a Research Associate in Ophthalmology. Prior to moving to SRI in 2019, she was a Research Assistant Professor at the University of Illinois, Chicago.
