Fluid intracavity laser diode (FILD) sensor
(2005) Kumar, Dhiraj, author; Lear, Kevin, advisor; Rocca, Jorge, committee member; Henry, Charles, committee member
Laser based microfluidic devices, especially ones in which a microfluidic channel is an integral part of the laser cavity, are very attractive for biomedical diagnostics applications. The fluid intracavity laser diode (FILD) sensor constructed in this research work is an electrically pumped vertical cavity surface emitting laser (VCSEL) based microfluidic device. It has the potential to detect different biological cells in a fluid. The FILD sensor was constructed by attaching a bottom emitting VCSEL above an external dielectric mirror with an intervening ~10 ?m thick photoresist spacer which forms the sidewall of the fluidic channel. The VCSEL contained a complete top DBR mirror and gain region, but only a partially reflecting bottom mirror so that the external dielectric mirror completed the resonator cavity. The external dielectric mirror was made on a BK7 polished substrate with a high reflective coating (~99%) at the laser wavelength (980nm). The sensor was assembled by heating the dielectric mirror with patterned photoresist at 125 °C and attaching the VCSEL die to the softened photoresist. The result was a closed fluidic cavity formed between the dielectric mirror and the VCSEL diode. This closed fluidic channel allowed fluids and other biological samples through the reservoirs to the cavity of the laser. Lasing operation of FILD sensors were observed under CW and pulsed input current conditions. Output power vs. input current characteristics of various FILD sensors were measured under pulsed, room temperature conditions, for different fluids inside the fluidic cavity. The majority of the sensors exhibited a trend of increase in slope efficiency and decrease in threshold current with increase in fluid index of the fluidic cavity. Spectral measurements of a FILD sensor were also performed, which showed ~1nm wavelength shift with change in homogeneous fluid index from 1 to 1.33. Modulation of transverse confinement of laser beam was also observed when 10 ?m diameter polystyrene spheres, used as prototype biological cells, were flown inside the FILD's fluidic cavity. Several theoretical phenomena were investigated to explain the modulation trends of FILD's output characteristics due to change in fluid index. Complete qualitative and quantitative analysis of these phenomena are presented in the form of a thesis chapter and appendices.

Angler workshop report: improving equity and participation in recreational fishing in Colorado
(2026-05) Lavoie, Anna, author; Teumer, Meghan, author; Colorado State University, publisher
On February 9, 2026 we held a workshop that brought together 13 participants from state agencies, nonprofits, community organizations, and recreation stakeholders to discuss barriers and opportunities related to increasing participation in recreational fishing among women and other underrepresented communities in Colorado. Workshop attendees worked in groups to identify barriers and solutions to inclusivity and access. Across groups, participants emphasized that barriers to participation are deeply interconnected, spanning structural, cultural, economic, informational, and institutional dimensions. Participants also identified collaborative and community-centered solutions that could improve long-term access and belonging.

Interdisciplinary analysis on the Iliad: character traits and their correlations with modern Western perceptions of strength and weakness
(2026-05) Simons, Katelynn, author; Fulford, Devon, advisor; Hutchins, Zach, committee member
The myths and culture of Ancient Greece have shaped, and continually shape, many aspects of the modern Western world. Therefore, it may also affect Western ideals of strength and weakness. Across the board, modernly and historically, Western societies tend to celebrate strength over weakness—strengths are meant to be celebrated and enriched, and weaknesses are meant to be minimized and overcome. If behaviors are misaligned with these sociocultural perceptions, the resulting discomfort—within the individual and others—may incite disturbances and conflicts. Furthermore, individuals tend to use these expectations and representations to shape their sense of self, including those present in entertainment media. The Iliad is an example of entertainment which was consumed in Ancient Greece and in the modern day, making it a relevant focal point of analysis. Using character traits and related plot progression, four sub-traits of strength and four sub-traits of weakness were extracted. When characters displayed sub-traits of strength, their actions were predominantly rewarded. Similarly, when characters displayed sub-traits of weakness, their actions were predominantly punished. These sub-traits, and textual context thereof, were individually compared against relevant, modern research findings on Western societal perceptions of strengths and weaknesses. All eight sub-traits experienced correlations with the reviewed research. Overall, textual evidence aligned with the sociocultural beliefs, behaviors, attitudes, and expectations found in the reviewed research on Western society—strengths were favored, weaknesses were unfavored, and correction is insighted when social expectations are broken. This analysis can be used to identify how historical cultures may correlate with modern ideals, and thus, how individuals may associate with representations in stories via those ideals. Findings are limited to correlational analysis of external research, as no experiments were conducted. Findings are, also, constrained to character traits, sub-traits, and related plot progressions in the Iliad. No other Greek poems, mythos, or literature were used in analysis.

Explore the air around you: check-out kit for 3rd through 8th grade students
(2024-01-01) Holmes, Maia, author
"This activity will help you explore some of the different particles that exist in the air but are too small to be seen with just your eye. Much of what we find in the air are small bits of larger things that are floating on air currents, like bits of dried plant material, dust, sand, and animal hair. However, some particles that can be found in the air are there because they use air to travel from one location to another, like plant pollen, spores of fungi, and certain viruses and bacteria. Most living things in the air are microbes."
