Hello everyone, I am Ram Ambre from India. I have completed my PhD from Taiwan and have postdoctoral research work experience from Taiwan, Sweden and United States. I am friendly and easy-going person, having a positive attitude towards work and life. Apart from work I like to spend time with my wife, kids, and friends. In the Worrell group I am involved in synthesis, characterization and application of CO releasing organic polymers.

I grew up in Carbondale, Illinois (not Chicago), then moved on to Tennessee for undergrad at Sewanee. There I majored in chemistry, worked in an inorganic lab, and spent my free time trail running on the Cumberland plateau. After graduating I headed to Denver to continue pursuing mountain related activities. In the Worrell lab I plan to work on organic synthesis with applications in polymer and materials science.

I was born and raised in Denver till I went to Michigan to attend Calvin University where I studied chemistry and found a real passion for organic synthesis.  Growing up in Colorado I enjoyed all of the outdoor activities that the state has to offer but I have a particular love for fly fishing and camping. In the Worrell Lab I plan to work on organic synthesis in the context of CO releasing polymers.

I was born and raised in Grand Rapids, Michigan, where I received my bachelor degree in chemistry from Grand Valley State University. Post graduation, I gained years of experience as an analytical chemist in the food industry and as a chemical engineer in the pressure-treated wood industry. I developed an interest in photopolymer chemistry after forming a joint venture with a specialty polymer company in Utah. Subsequently, when I visited Colorado and Utah in 2022 for business, I fell in love with the mountains and landscapes. As a result, I decided to pursue a PhD at the University of Denver to further my knowledge of photopolymer chemistry and to enjoy the beauty of Colorado. My function in the Worrell lab is to advance their novel photopolymer systems.

Undergraduate Students

Viv Lawless (U4)

Office: SGM 229, Lab: SGM 239/243

I’m originally from Columbus, Ohio but chose University of Denver due to my love for the outdoors and the amount of family I have in Denver. I am a Biochemistry major with a minor in biology and medical physics. My true passion is chemistry but I am highly interested in the application of chemistry in medicine which led me to biochem and the use of polymers in the biomedical field. In the Worrell Lab I work with Riya Joshi and Mckenna Hanson on polymer production for undergraduate labs and am doing in situ kinetic experiments.
