Achievements

Ho Yi Wan

Wildlife

Dr. Ho Yi Wan received a grant from the CSU Agricultural Research Institute to support research on a collaborative project that will develop a viable business plan associated with mass timber production in the coastal region of northern California. Dr. Wan and his lab will be responsible for assessing some of the ecological benefits of this plan, primarily with regards to wildfire risks reduction from timber harvest.

Erin Kelly, Benjamin Graham, and Jeff Kane

Forestry, Fire & Rangeland Management

Drs. Erin Kelly, Benjamin Graham, and Jeff Kane received a grant from the Joint Fire Science Program (administered by the Departments of Interior and Agriculture) to support a study on community recovery after wildfires, and how recovery can lead to social-ecological resilience. The study will look into what recovery looks like in communities impacted by wildfires, the networks within communities present for recovery, and the resources available to implement community recovery. Findings will be useful for policy makers trying to create funding, regulatory, and other policy mechanisms to facilitate community recovery, and organizations working toward social-ecological resilience in fire-prone landscapes.

Regina Khoury and Sarah Leidinger

Geology

Graduate students Regina Khoury and Sarah Leidinger (Geology) are the 2022-2023 recipients of the $1,500 Richard Chambers Memorial Scholarships from the Northern California Geological Society. Regina Khoury's MS thesis proposal is titled “Pre-Eruptive Storage Conditions of Magmas Erupted During the ~12ka Flare Up of Medicine Lake Volcano, CA.” Her advisor is Dr. Brandon L. Browne in Geology. Sarah Leidinger's MS thesis proposal is titled “Bathymetry and carbon accumulation rate of a rare Northern California coastal peatland.” Her advisor is Dr. Laura Levy in Geology. Congratulations Regina and Sarah! 

Hunter Harrill

Forestry, Fire & Rangeland Management

Hunter Harrill (Forestry) was a co-author of a recently published article titled "Operational Analysis of Grapple Yarding in New Zealand: A Case Study of Three Mechanized Harvesting Operations"  in the journal Forests. https://doi.org/10.3390/f14020190

Silvia Pavan

Biological Sciences

Dr. Silvia Pavan received a grant from the National Science Foundation to implement a project that will digitize and georeference Cal Poly Humboldt’s mammal collection. The project will be part of a collaborative effort under the Ranges Thematic Collections Network (Ranges TCN), an initiative lead by the University of North Carolina, to digitize and mobilize trait data from mammalian museum specimens from across the American West, including standard external morphological measurements, reproductive and life history observations, and information on ecological associations. Resulting trait datasets will support next-generation anatomical and evolutionary research, and provide baselines for future population monitoring efforts.

Erik S. Jules

Biological Sciences

Erik Jules (Biological Sciences) published a paper with ten Humboldt student co-authors in the American Journal of Botany (doi.org/10.1002/ajb2.16112). The study -- titled "Genotype accounts for intraspecific variation in the timing and duration of life cycle events" -- was an experimental study of willows covering an area approximately the size of a football field. The results showed that the timing of key life events, such as leaf emergence, flowering, and fruit set, are all heritable traits, indicating that natural selection could favor some individuals under changing climate conditions. Of the ten students, six went onto graduate school after leaving Humboldt.

Diksha Shrestha, Jun Ou, Ariel Rogers, Amani Jereb, Deborah Okyere, Jingyi Chen, Yong Wang

Environmental Resources 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.

Environmental Resources 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

Allyson Carroll

Forestry, Fire & Rangeland Management

Allyson Carroll (research associate) received a grant from the United States Geological Survey (USGS) to support research that will use redwood tree rings to date earthquakes on the northern San Andreas Fault. Tree ring signals, such as changes in growth and dates of reiterated trunks, will be used to constrain the year of the large magnitude event that occurred prior to the 1906 earthquake. Project findings will improve earthquake recurrence models for this region. Collaborators include Dr. Stephen Sillett and Marie Antoine at Cal Poly Humboldt, as well as Dr. Belle Philibosian at USGS and Dr. Ozgur Kozaci.

Hunter Harrill

Forestry, Fire & Rangeland Management

Dr. Hunter Harrill (Forestry) was invited to give a presentation titled "Grapple Yarding Productivity Studies." His presentation was part of a panel on Grapple Yarding at the Western Region Council on Forest Engineering (WR.COFE) annual meeting on January 12th, 2023, in Lebanon, Oregon.
