December 2020 – Cristina Vidal

0 279

Cristina Vidal is an Assistant Professor at the of Iowa College of Dentistry, Iowa City. Vidal obtained her D.D.S. and M.S. in Dental Sciences (Restorative Dentistry) from the São Paulo State University, Araçatuba School of Dentistry, Brazil and her Ph.D. in Dental Materials from the University of Campinas, Piracicaba School of Dentistry, Brazil. She completed a two-year post-doctoral research training at the University of Illinois at Chicago in 2014. 

Vidal’s research interests are on endogenous mechanisms that promote degradation of dentin organic matrix in caries lesions and in adhesive interfaces. Her previous work was focused on the presence and activity of different families of endogenous proteases in sound and carious dentin. Moreover, she has expertise in therapies to inhibit collagen degradation, strengthen dentin mechanical properties and increase tissue biostability by promoting collagen cross-linking with natural-derived compounds. Vidal’s recent research projects aim to characterize host-microbiome interactions in dentin caries progression to ultimately develop novel therapies that modulate proteases involved in dentin degradation and repair processes. With more than 35 peer-reviewed manuscripts published in the last 10 years, Vidal collaborates with different research groups in U.S., Brazil and Finland. Vidal served as Vice-president and President of the Iowa Section of AADR in 2019 and 2020 and currently is a member of the IADR Awards Review Committee.  

November 2020 – Susana Maria Salazar Marocho

0 343

Susana Maria Salazar Marocho earned her B.D.S. from the University of San Martin de Porre, Chiclayo, Peru and her M.S., Ph.D. and completed her post-doctoral studies at the State University of Sao Paulo (UNESP, Campus São José dos Campos), Brazil. Salazar Marocho continued her postdoctoral studies at the  University of Mississippi, Jackson where she is now an Assistant Professor in the School of Dentistry. Salazar Marocho’s research focuses on dental ceramics, with an emphasis on their characterization, bonding, mechanical behavior, reliability, failure mechanisms and lifetime. Utilizing an integrative approach including standard and clinically relevant specimens, her research group is developing less expensive, less time-consuming and non-destructive methods for removal of high-strength ceramic restorations by using different settings of an erbium, chromium-doped: yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser.

October 2020 – Bruno Lima

0 443

Bruno Lima is a research assistant professor at the University of Minnesota, School of Dentistry in the Department of Diagnostic and Biological Sciences, Minneapolis. Lima received his dental degree from the Federal University of Rio Grande do Norte in Brazil and his Ph.D. from the Department of Microbiology and Immunology at Loyola University, Chicago. His research focuses on understanding how bacteria interact with their environment and the consequence of these interactions on their physiology. As a dentist, Lima is particularly interested in studying how different environmental interactions affect dental plaque development and whether these interactions can be manipulated to promote oral health. Lima has authored several peer-reviewed articles, he is currently the recipient of a career development award (K08) from the National Institute of Dental and Craniofacial Research (NIDCR) and was recently selected as the recipient of the 2020 American Association of Dental Research (AADR)/Procter & Gamble Underrepresented Faculty Research Fellowship.

September 2020 – Karen DeRocher

0 413

Karen A. DeRocher obtained her B.S. in materials engineering from Iowa State University, Ames, in 2013. DeRocher’s undergraduate research involved investigating the oxidation behavior of a high temperature metal alloy. She received her Ph.D. from the Department of Materials Science and Engineering at Northwestern University, Evanston, Ill. At Northwestern University her research focused on characterizing enamel on different length scales. Primarily, she was involved in investigating the chemical gradients inside human enamel crystallites and the implications that may have on their chemical and mechanical properties. Additionally, she worked on X-ray diffraction studies investigating the crystallographic orientation of crystallites across enamel rods and comparison to interrod enamel. 

August 2020 – Marco C. Bottino

0 640

Marco C. Bottino is an Associate Professor with tenure in the Department of Cariology, Restorative Sciences and Endodontics and Director of the Postgraduate Program in Regenerative Dentistry at the University of Michigan School of Dentistry, Ann Arbor.

Bottino received his DDS from the Universidade Paulista, São Paulo, Brazil, his MSc in Nuclear Technology (Materials) from the University of São Paulo (Institute for Energy & Nuclear Research, Brazil), and his PhD in Materials Science from The University of Alabama at Birmingham.

Bottino’s research focuses on the development of drug delivery systems for ablating oral infection and stimulating dental tissue regeneration. Recently, his laboratory has expanded its program to include generating personalized and tissue-specific strategies to regenerate soft and hard tissues by leveraging innovative bioprinting technologies. Bottino served as President of the IADR Dental Materials Group and is a winner of the prestigious IADR Centennial Emerging Leaders Award.
