Silene californica (Caryophyllaceae) -  My thesis research investigates the identity of populations of Silene formerly known as Silene californica, treated as Silene laciniata subsp. californica in The Jepson Manual 2nd Ed. and The Flora of North America, with affinities to Silene hookeri  and  the recently described Silene serpentinicola.

Linanthus dichotomus (Polemoniaceae) - A molecular based systematic study of day and night blooming populations of Linanthus dichotmus based on the ITS region of the nuclear genome to determine possible evolutionary and biogeographic patterns of blooming syndromes.

Plant diversity of montane meadows - An investigation of factors contributing to plant diversity in meadows of the Little Truckee River drainage, east slope of the northern Sierra Nevada. San Francisco State University and The Nature Conservancy.

Flora of Angel Island  - An ongoing, grant awarded, modern floristic survey of Angel Island post fire and post non-native timber removal- inspired by and conceived as a comparison to the historical and monumental survey completed by James Douglas Ripley in 1969.

Thermopsis californica (Fabaceae) - An investigation of the current taxonomic treatment of Thermopsis in California and the biogeographic implications of infraspecific identities in T. californica.
