Lavoisier Award Recipients

Todd Buley, Global Application Leader; Electronics & Industrial, Chemical Mechanical Planarization Technologies; Newark, DE – Buley is a global expert in Chemical Mechanical Planarization (CMP) materials and application engineering with more than 30 years of experience in technology.  Enabled by insights drawn from close partnerships with customers, Buley has commercialized numerous semiconductor processes, CMP Pad & Slurry products, and specified countless processes for use of those products – all which have contributed significant value.  His contributions include being among the first in the industry to develop a CMP process to fabricate DRAM chips, pioneering work with pad grooves and conditioning, and novel slurry technologies. Buley also pioneered a CMP fundamentals toolbox and customer engagement model, including training for customers, to develop and specify numerous CMP processes with DuPont Pads & Slurries, supporting the business as a recognized leader in the pad market and delivering significant and sustained growth in sales over the last 20 years.

Theresa (Teri) Weston, DuPont Laureate (retired); Water & Protection, Shelter Solutions; Richmond, VA – Weston is a true innovation leader and trailblazer. Over her 35-year career in the construction space, she elevated the role of building science from a troubleshooting tool to a strategic capability with our customers.  Weston leveraged her expertise with Tyvek® water/air barrier solutions to enable products that today are market-leading materials.  This includes innovations in the North American HomeWrap® products, non-residential CommercialWrap®, the industry’s first drainage wrap (StuccoWrap®) and the first DuPont flashing product (FlexWrap®).  Her external technical credibility was beneficial when engaging with code/standards groups and national committees. Weston also played a key role in the integration and establishment of the Shelter business following the Dow-DuPont merger, focusing on building science-based common ground that resulted in a wide array of building system solutions and ultimately synergistic growth. 


Pedersen Award Recipients

Chris Bish, Technical Laureate; Electronics & Industrial, Industrial Solutions; Wilmington, DE – Bish is renowned for developing new crosslinking chemistries to fully exploit the performance advantages of Kalrez®.  These crosslinkers enable the best high-temperature stability of any similar material, the broadest possible chemical resistance, and combinations of both of those properties.  This technology contributed to the 400 percent annual revenue growth of the Kalrez® business over the past 25 years. 

Carmen Covelli, Technical Laureate; Mobility & Materials, Hytrel®; Wilmington, DE – Covelli innovates across applied polymer, fiber, and formulation sciences to develop new products for the Rynite®, Crastin®, Hytrel® and Kevlar® product lines  and has made significant contributions to prior DuPont products such as Sorona®  polymer and Lycra® fiber. Covelli’s innovations have contributed to significant growth in sales to textile, carpet, ballistics, and resins applications. In addition to her technical prowess, she is highly valued for her boundless enthusiasm, leadership and passion for sustainability, mentorship, and talent recruitment. 

Tomoki Kurihara, Lead Scientist; Electronics & Industrial, Semiconductor Technologies; Niigata, Japan – Kurihara leverages deep expertise in materials and formulation science to develop several world-class photoresists and bottom antireflective coatings that contributed significantly to business revenue. His close collaboration with key customers resulted in innovative materials that enable high-volume manufacturing of electronic devices ranging from smartphones to high-performance computing to cutting-edge wearables with smaller size, faster speed, and lower power consumption. 

Xiaoqing Li, Principal Scientist; Electronics & Industrial, Industrial Solutions; Wilmington, DE – Li is renowned for creating two foundational polymer platform technologies within the DuPont Digital Inks business that continue to enable differentiating product offerings today. The development of waterborne polyurethane dispersion binders and crosslinked pigment dispersions enabled success in direct-to-garment apparel printing, roll-to-roll textile printing for fashion, upholstery and home furnishings, and commercial applications such as transactional printing.
