Kathryn Ann Whitehead (born 1980) is an American chemical engineer who is a professor at Carnegie Mellon University. Her research considers the development of nanomaterial-based drug delivery systems for gene therapy, [1] oral macromolecular delivery systems, [2] and maternal and infant therapeutics. [3] She is an elected Fellow of the American Institute for Medical and Biological Engineering in 2021 [4] and Fellow of the Controlled Release Society. [5]
Whitehead is from Allentown, Pennsylvania. [6] She earned her bachelor's degree in chemical engineering at the University of Delaware, [6] then moved to the University of California, Santa Barbara, where she studied methods to improve the oral delivery of macromolecules. [7] Whitehead was a postdoctoral researcher at the Koch Institute for Integrative Cancer Research, where she worked alongside Robert S. Langer on RNA interference therapeutics. [8]
Whitehead's research considers the development of drug delivery systems for gene therapy. [9] She is interested in the development of nanoparticle materials to deliver messenger RNA (mRNA) to specific cells. [10] Targeted mRNA delivery provides physicians with a personalized strategy to treat genetic disorders. [11] Alongside mRNA, Whitehead has studied small interfering RNA, which can be used to control gene expression. [12] In general, mRNA promotes gene expression, whilst siRNA is used to silence over-expressed genes. [13] She focuses on the development of delivery systems for leukocytes (including B cells) and intestinal epithelium. [6] [14] A challenge with using mRNA for therapeutic purposes is that the body often recognizes intruder mRNA and attacks it, triggering an immune response. [13] She worked with Katalin Karikó and Drew Weissman on the development of the lipid nanoparticles that enabled the mRNA-based COVID-19 vaccines. [15] [16]
In an attempt to better design drug delivery systems, Whitehead has investigated the cellular components of breast milk. [17] [18] She is interested in whether it is possible to genetically engineer cells to treat children's allergies, or orally administer vaccines to infants. [17]
Whitehead is passionate about science communication and improving public trust in science. [19] In 202, she delivered a TED talk on lipid nanoparticles and how mRNA will transform biology. [20] In 2022, Whitehead delivered the convocation address at the Carnegie Mellon University. [21]
Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA at first non-coding RNA molecules, typically 20–24 base pairs in length, similar to miRNA, and operating within the RNA interference (RNAi) pathway. It interferes with the expression of specific genes with complementary nucleotide sequences by degrading mRNA after transcription, preventing translation. It was discovered in 1998, by Andrew Fire at Carnegie Institution for Science in Washington DC and Craig Mello at University of Massachusetts in Worcester.
Drug delivery refers to approaches, formulations, manufacturing techniques, storage systems, and technologies involved in transporting a pharmaceutical compound to its target site to achieve a desired therapeutic effect. Principles related to drug preparation, route of administration, site-specific targeting, metabolism, and toxicity are used to optimize efficacy and safety, and to improve patient convenience and compliance. Drug delivery is aimed at altering a drug's pharmacokinetics and specificity by formulating it with different excipients, drug carriers, and medical devices. There is additional emphasis on increasing the bioavailability and duration of action of a drug to improve therapeutic outcomes. Some research has also been focused on improving safety for the person administering the medication. For example, several types of microneedle patches have been developed for administering vaccines and other medications to reduce the risk of needlestick injury.
The Dickson Prize in Medicine and the Dickson Prize in Science were both established in 1969 by Joseph Z. Dickson and Agnes Fischer Dickson.
Lipid nanoparticles (LNPs) are nanoparticles composed of lipids. They are a novel pharmaceutical drug delivery system, and a novel pharmaceutical formulation. LNPs as a drug delivery vehicle were first approved in 2018 for the siRNA drug Onpattro. LNPs became more widely known in late 2020, as some COVID-19 vaccines that use RNA vaccine technology coat the fragile mRNA strands with PEGylated lipid nanoparticles as their delivery vehicle.

An mRNAvaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. The vaccine delivers molecules of antigen-encoding mRNA into immune cells, which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen or by a cancer cell. These protein molecules stimulate an adaptive immune response that teaches the body to identify and destroy the corresponding pathogen or cancer cells. The mRNA is delivered by a co-formulation of the RNA encapsulated in lipid nanoparticles that protect the RNA strands and help their absorption into the cells.

ALC-0315 is a synthetic lipid. A colorless oily material, it has attracted attention as a component of the SARS-CoV-2 vaccine, BNT162b2, from BioNTech and Pfizer. Specifically, it is one of four components that form lipid nanoparticles (LNPs), which encapsulate and protect the otherwise fragile mRNA that is the active ingredient in these drugs. These nanoparticles promote the uptake of therapeutically effective nucleic acids such as oligonucleotides or mRNA both in vitro and in vivo.

Intracellular delivery is the process of introducing external materials into living cells. Materials that are delivered into cells include nucleic acids, proteins, peptides, impermeable small molecules, synthetic nanomaterials, organelles, and micron-scale tracers, devices and objects. Such molecules and materials can be used to investigate cellular behavior, engineer cell operations or correct a pathological function.

The company was established in February 2009 to specialize in the development of delivery systems for nucleic acid therapeutics based on lipid nanoparticle (LNP) technology, a key component of the mRNA vaccines deployed for COVID-19.
Selective organ targeting (SORT) is a novel approach in the field of targeted drug delivery that systematically engineers multiple classes of lipid nanoparticles (LNPs) to enable targeted delivery of therapeutics to specific organs in the body. The SORT molecule alters tissue tropism by adjusting the composition and physical characteristics of the nanoparticle. Adding a permanently cationic lipid, a permanently anionic lipid, or ionizable amino lipid increases delivery to the lung, spleen, and liver, respectively. SORT LNPs utilize SORT molecules to accurately tune and mediate gene delivery and editing, resulting in predictable and manageable protein synthesis from mRNA in particular organ(s), which can potentially improve the efficacy of drugs while reducing side effects.
