Biography
John P. Jasper, Ph.D. [MIT (Cambridge, MA) and Woods Hole Oceanographic Institution (Woods Hole, MA)] is the Chief Scientific Officer of Nature’s Fingerprint® / MIT LLC of Niantic, Connecticut (www.NaturesFingerprint.com). He received his B.A. in Geophysical Sciences and Biological Sciences from The University of Chicago in 1981 and his Ph.D. from MIT/WHOI in Marine Organic Chemistry in 1988. With more than 38 publications in organic and isotope geochemistry and in bio/pharmaceutical chemistry, he has spent the last 30 years in the pharmaceutical industry (i) at Pfizer / Cultor where he developed new methods for measuring complex mixtures of synthetic triglycerides, (ii) at Drumbeat Dimensions Inc., a pharmaceutical advisory firm, where he developed the Scientific Validation Parameters employed in major pharmaceutical companies and many other standardized guidelines, and (iii) at Nature’s Finger-print® / MIT LLC where he has developed the use of natural stable isotopes as tracers of Product and Process Authentication (i.e., Pharmaceutical Anticounterfeiting / Process Patent Protection and Process Analytical Chemistry, PAC). The work in Process Patent Protection has already extended the patent life of biopharmaceuticals valued at more than $2 billion. More recently, MIT LLC has developed the directed synthesis of biopharmaceuticals (or, Molecular Isotopic Engineering, MIE) for reasons of product authentication, security, and potential intellectual-property protection. In 2018, he was elected Fellow of The Explorers Club for his molecular-isotopic paleo-PCO2 research which formed the basis for molecular-isotopic batch-process understanding work that was published in Pharma Manufacturing in 2024.
Presentation
Basic principles of the use of natural-abundance stable-isotope chemistry have allowed us to address significant problems in the areas of paleo-PCO2 reconstruction as well as industrial product and process authentication. After having completed his doctoral research (MIT/WHOI Chemical Oceanography, 1988) on the quantitative comparison of bulk-isotopic tracers to specific biomarker compounds, Jasper took his suite of samples from an ~210-m sediment core which spanned the last ~100 kyrBP from the Pigmy Basin in the northern Gulf of Mexico to John Hayes’ Biogeochemical Laboratories (IU-Bloomington). Calibrating the GOM sedimentary alkenone-isotope-derived record of the Photosynthetic Isotope Effect to an ~2500-m Antarctic ice-core record of CO2 gas, Jasper & Hayes developed the alkenone-isotopic PCO2 method (Nature, 1990) which has formed the basis of further PCO2 reconstruction which has spanned the last 500 Myr (Witkowski et al., 2018, Sci. Adv.). For his global-scale work on paleo-PCO2 reconstruction, Jasper was elected as a Fellow of The Explorers Club in 2018. More recently, the alkenone-isotopic PCO2 method significantly contributed to major paper on Cenozoic (0-66 MyrBP) PCO2 reconstruction (Hoenisch, Jasper, Pearson…et al., Science, 2023).
Since 1999, Jasper and colleagues, John M. Hayes (WHOI), Ann Pearson (Harvard EAPS), and Anthony Sabatelli (Wiggin & Dana, LLP) have largely developed the field of industrial-chemical natural-abundance stable-isotopic product and process understanding. With concepts learned in paleo-PCO2 reconstruction, MIT LLC was granted patents in areas of product and process understanding. That work has permitted use in product authentication and anticounterfeiting as well as in process understanding and process patent infringement. Most recently, we are working in the area of Batch Process Understanding (BPU) which, in its first application to a suite of pharmaceutical products, revealed batch shifting in the records as well as batch mixing of products. We are presently advocating further investigation and application of BPU.

PRESENTATION
Transient Electronics – From Bioelectronic Medicines to Environmental Monitors
A remarkable feature of modern integrated circuit technology is its ability to operate in a stable fashion, almost indefinitely, without physical or chemical change. Recently developed classes of electronic materials and manufacturing approaches create an opportunity to engineer the opposite outcome, in the form of ‘transient’ devices that dissolve, disintegrate, degrade or otherwise physically disappear at triggered times or with controlled rates. Water-soluble transient electronic devices serve as the foundations for applications in zero-impact environmental monitors, 'green' consumer electronic gadgetry and bio-resorbable medical implants. This talk describes the essential concepts in materials science, electrical engineering and assembly techniques for bio/ecoresorbable electronics in 2D and 3D formats and with a range of functions. Wireless temporary pacemakers that minimize risks after cardiac surgeries and passive microfliers that enable tracking of environmental processes represent some recent system level examples.

Brooke Kammrath, Ph.D. - May 25th, 5:30-9:00pm at Eli’s on Whitney in Hamden
“Better Justice with Portable Spectrometers”
Advancements in the miniaturization of instrumentation are carrying spectroscopy beyond the laboratory to deliver analytical capabilities directly to the sample. Meaningful societal implications have resulted from the development of varied applications of portable spectroscopy and spectrometry in diverse industries including, but not limited to chemical, cultural heritage, food science, geology, archaeology, hazardous materials response, military, and forensic science. Although not their primary purpose, portable spectrometers are tools with important implications for the promotion of social justice through rapid, reliable and objective science. Portable spectrometers provide swift access to better science thus providing a tool for realizing the goal of social justice to reduce human suffering through equality and justice. Whether it be through providing more reliable and objective real-time information regarding the identification of a suspected illicit drug sample than currently employed colorimetric field tests, or ensuring equal access to verified medicines through effective counterfeit pharmaceutical detection operations, portable spectrometers are proving to be valuable tools in the fight for equality and justice. This presentation will highlight applications of portable spectroscopy and spectrometry in the field detection of illicit and counterfeit drugs which have notable effects on the delivery of improved criminal and social justice.

About the Talk:
Science itself is never inherently bad or evil. However, it is easy to do sloppy science, misrepresent science, ignore racial and gender inequities in science or misuse science, and that is what I would call bad science. As science grows bigger and more powerful, these abuses escalate proportionally. This leads to mistrust of science at just the time when it is most important for scientists and nonscientists to find a consensus on sensitive issues. Some of the most crucial issues of our time―climate change, vaccines, and genetically modified organisms―have become prime targets for concerted disinformation campaigns. Fake news, pseudoscience, and quackery have spread through society from social media all the way to Congress. Where does it all come from?

“Chemically-Recyclable Polymer Materials via Modern Polymer Chemistry”
Hao Sun, PhD - Assistant Professor in the Chemistry Department at the University of New Haven
Over the past century, plastic materials have infiltrated into every facet of our society and become an essential part of our daily life. However, the current commercial plastics are considered as “forever materials” because of their extremely slow degradation in nature. At the end of their useful life, plastic wastes are typically landfilled or incinerated, causing serious issues to the ecosystems and human health. To tackle this challenge, my research team at the University of New Haven is developing the next-generation polymer materials that are degradable, chemically-recyclable, and possess excellent mechanical/thermal properties akin to current commercial polymers. Specifically, we leverage our multidisciplinary knowledge of polymer chemistry and material science to design novel polymer structures that can easily depolymerize back into original monomers under mild conditions. The regenerated monomers can be reused to produce the polymer again, achieving a circular economy of polymer plastics.
Dr. Hao Sun is an organic and polymer chemist. He is currently an assistant professor of Chemistry at the University of New Haven. His research program harnesses macromolecular approaches to addressing challenges in global health and sustainability. In particular, his group leverages state-of-the-art synthetic polymer chemistry to design next-generation polymer materials, generate polymer-biomolecule conjugates, and gain fundamental knowledge of structure-property relationships for polymer materials in specific applications. Several areas in the intersection of synthetic polymer chemistry, materials, and biomedicine are being investigated, with particular focus on those most closely related to environmental and biomedical applications. Current research interests of Sun research group are centered in: (1) developing chemically-recyclable polymer materials for a sustainable future; (2) developing modular and scalable approach for biopolymer-based delivery systems of therapeutics (e.g., gene, peptides, and proteins).

“Additive Manufacturing of Functional Materials: From Electronics to Edible Products”
Anson Ma PhD - Site Director, National Science Foundation (NSF) SHAP3D center for additive manufacturing, UTC Professor in Engineering Innovation - University of Connecticut
Additive manufacturing (AM), also commonly referred to as “3D printing”, uses computer-aided design to build objects layer-wise or drop-wise. AM complements more conventional subtractive manufacturing methods, where unwanted material is removed from a piece of feedstock material by cutting, drilling, or grinding. AM has been successfully used to create complex, topologically optimized parts that are otherwise extremely difficult or impossible to manufacture using conventional methods. AM is especially well-suited for distributed manufacturing, mass customization, reducing tooling costs, and minimizing material wastage. This presentation will highlight some of our recent AM research activities, spanning from printing polymer composites, sensors, and magnets to food and drug tablets, using a variety of AM techniques, such as fused deposition modeling, digital light processing, direct ink writing, and binder jetting. While the need for 3D printing is motivated differently by the specific applications, the key to success is founded on understanding the fundamental science of the AM processes. In this presentation, we will also share the lessons learnt during the development of a pilot-scale HuskyJet 3D printer. With the open architecture of this printer, we have further explored a rather ambitious concept of “autonomous 3D printing” to speed up the optimization process, leveraging the latest (near) real-time, in-situ metrology and machine learning methods.

Laura Cisneros and Nicole Freidenfelds - March 7th, 2022 at 7pm
The University of Connecticut’s Conservation Training Partnerships program uses an innovative intergenerational partnership framework that connects teens and adults and empowers them to understand and address local environmental issues. First, our intergenerational teams (e.g., high school students and adult volunteers) attend a two-day workshop that teaches them practical approaches to conservation science and geospatial technology. Then each teen-adult team designs and implements a local project that addresses a real community environmental need, leveraging their new technological and conservation toolkit. During this presentation, we will first share our programmatic model, outline and discuss how our design principles and communication pillars were developed, and demonstrate how they are interwoven into program activities and project support to facilitate the successful completion of teen-adult conservation efforts. These design principles and communication pillars aim to establish collaborative team partnership norms that resist traditional hierarchical teen-adult relationships. They also consider how participants can draw on their interests and experiences and connect with conservation science disciplinary knowledge and practices to accomplish meaningful pursuits. The guiding principles we propose can help contribute to and enhance community-driven local environmental outcomes.

ACS New Haven is sponsoring a talk by Stephen Gephard on Thursday November 11th at 6pm
Anadromous fish are species that migrate from saltwater to freshwater to spawn. Examples include salmon, shad, river herring, striped bass and sturgeon. These fish typically leave natal freshwater streams as relatively small juveniles and return after years in the ocean as large adults. The adults generally return to the same freshwater body of water from which they departed as juveniles. This life history requires two complex processes: physiologically changing from a freshwater fish to a saltwater fish and then vice versa, and finding their way 'home'. The latter mechanism is referred to as imprinting/homing and it takes advantage of the unique organic chemical components in the water of the home streams. This mechanism can be disrupted by both natural substances and anthropogenic chemicals in the water. Conservation of these important 'runs' of fish require that our waterways remain free of not only the well-known pollutants such as sewage but also some lesser known covert chemicals that can do damage at extremely low concentrations.

"The Chemistry (and a little bit of biology) of Eggshells”
Christian Brückner, University of Connecticut, Department of Chemistry
Bird eggs are filled with wonder, deep symbolism, and culinary delight. Eggshells are also fascinating from biological and chemical points of view. This talk will be richly illustrated, primarily non-technical, and geared toward a science-curious audience. I will briefly introduce eggshell shapes, materials, and eggshell colorings from the points of view of a life-long but non-expert birder and synthetic organic chemist. Drawn from well-established knowledge as well as most recent findings, biological function is linked to mechanical principles, color theory, as well as materials and dye chemistry. Special focus will be on the chemistry of eggshell pigments and their link to ‘the pigments of life’.

ACS Connecticut Valley Section (CVS) is sponsoring a talk by Dr. Mingxu You on February 23rd, 2022 at 7pm.
“Cellular Imaging and Regulation with Nucleic Acids”
Abstract:
Sensors that can report the distribution and flux of cellular metabolites and signaling molecules are critical tools in studying biology. Based on emerging genetically encoded fluorescent RNA molecules, I will first introduce an advanced sensor platform for the quantitative and sensitive detection of a broad range of cellular targets. In the second half of this talk, DNA-based tools will be described for imaging some previously undetectable biophysical events in live cell membranes, including intercellular mechanical forces and dynamic lipid-lipid and lipid-protein interactions. Our goal is to develop next-generation platforms to study cell biology and disease, based on the building block of life – nucleic acids.
