Diksha Shrestha, Jun Ou, Ariel Rogers, Amani Jereb, Deborah Okyere, Jingyi Chen, Yong Wang
School of Engineering
In collaboration with University of Arkansas, we recently published a journal paper at Colloids and Surfaces B: Biointerfaces. In this work, we mimicked soil-like porous media by microspheres at various densitiesm, simultaneously characterized the pores and tracked bacterial motion in pores, quantified changes in bacterial swimming due to pore-scale confinement, established correlation between bacterial trapping and geometric confinement, and proposed the importance of distinguishing bacterial motility from mobility.

School of Engineering
Dr. Jun Ou, as a corresponding author, recently published a journal article which investigated the industrial scale Counter Pressure Casting (CPC) process at the journal Metallurgical and Materials Transactions B. Using an approach that combines advanced numerical modelling and industrial data acquisition, the work enhances the understanding of how the casting/die interface gap and pressure impact the temperature field in the casting.
This article was selected as the editor's choice and this honour is reflective of the work's comprehensive nature and its overall excellence
Bonnie Ludka, Adam Young, Robert Guza, William O’Reilly, Mark Merrifield
School of Engineering
Dr. Bonnie Ludka and colleagues have published a paper in Coastal Engineering titled "Alongshore variability of a southern California beach, before and after nourishment." Their work investigates the link between wave-driven alongshore currents and hotspots of beach erosion and accretion on a southern California beach. Additionally, they analyze the effectiveness (both positive and negative impacts) of beach nourishment as a coastal management technique to manage the hotspots. The influence of alongshore sand transport on the migration and closure of a nearby river mouth is also discussed.
Robert Gearhart
School of Engineering
Dr. Robert Gearheart received a grant from the City of Arcata to continue the implementation of a wastewater engineering project. The project focuses on the ongoing effort to ensure that the upgrade of the City of Arcata’s Wastewater Treatment maintains the use of constructed wetland as the principle treatment process, supplies critical habitat for wildlife, and supports environmental education. Cal Poly Humboldt students from the Environmental Resources Engineering Department will get hands-on experience working with City staff at the Arcata Marsh Research Institute. Results from the studies will be shared with City staff and their consultants.
Carisse Geronimo, Dr. Sintana Vergara, Dr. Charles Chamberlin, Dr. Kevin Fingerman
School of Engineering
Carisse Geronimo, graduate of the Energy Technology and Policy program in the Environmental Resources Engineering department (2020) and current research engineer at the Schatz Energy Research Center, has published an article in the journal "Fuel" with Drs. Sintana Vergara, Charles Chamberlin, and Kevin Fingerman. The article is titled "Overlooked emissions: influence of environmental variables on greenhouse gas generation from woody biomass storage" and is available here: (https://doi.org/10.1016/j.fuel.2022.123839)
Kushal Adhikari
School of Engineering
Dr. Kushal Adhikari, Faculty and Research Associate-Environmental Resources Engineering, along with four other speakers served as a panelist in Transformative Innovation Policy Consortium 2022.
Dr. Adhikari shared his opinion on how the academic research and knowledge can be transformed and implemented at policy level. Also, he shared his thoughts on how the networking can serve as a platform for knowledge transformation. Attached is the link for the session led by Dr. Adhikari and the group.

Kushal Adhikari
School of Engineering
Dr. Kushal Adhikari, Faculty and Research Associate-Environmental Resources Engineering, in collaboration with Texas Tech University recently published the article, "Minimizing Errors in the Prediction of Water Levels Using Kriging Technique in Residuals of the Groundwater Model" in Water journal.
The article presents the water community with a new and integrated approach for improved monitoring of groundwater resources. The prediction error was reduced from ~31 m to less than 5 m after the application of integrated approach. This will lead to sustainable use of groundwater resources while also aiding in efficient and effective conjunctive management of surface and groundwater resources.

Lonny Grafman
School of Engineering
Lonny Grafman co-authored a new book with Dr. Joshua Pearce on how communities come together to harness the power of the sun and how other people can do it as well.
Thanks to a partnership with Humboldt State Press and the Appropedia Foundation with the backing of a very successful Kickstarter campaign, this book is available free to all that need it.

Kushal Adhikari, Clifford B Fedler, Alireza Asadi
School of Engineering
Adhikari (ERE Faculty) and researchers from Texas Tech University recently published an article on design configuration and flow dynamics of Pond-In-Pond (PIP) wastewater treatment system for reuse. The findings showed that the PIP offers more advantage over traditional ponds and thus may be a potential alternative to existing treatment systems. For more information, please refer to:
