Mentor of over 90+ undergraduate students doing research in my lab

Mentor of over 20+ graduate students at Universities in Puerto Rico (UPR, Univ. del Turabo, Metropolitan Univ.) and Colombia.

Publications I have published over 70+ peer reviewed papers and have a been cited at least 2150 (Google scholar).  The paper which has had most impact is “Variation in sexual reproduction in orchids and its evolutionary consequences: a spasmodic journey to diversification”. Biological Journal of Linnean Society, 2005, Tremblay, RL J. D. Ackerman, J. K. Zimmerman & R. Calvo.   with over 630 citations. This paper reviews the literature on reproductive processes in orchids and suggest that cladogenesis and likely the result of the great number of species in this family is likely a result of not only Natural Selection, but an interplay of Natural Selection and Genetic Drift.

Another important paper is “Bayesian Estimation of transition probabilities in seven small lithophytic orchid populations: maximizing data availability from small samples”. Tremblay and McCarthy, 2014.  This paper is unique in that is resolves one of the major issues of dealing with rare species, that is the lack of data, in this case we show that we can use information from other transitions and populations to estimate the most likely parameters.

In this following paper, improving the power of population projections: a unified approach to asymptotic and transient population dynamics. Annals of Botany. DOI: 10.1093/aob/mcv031., Tremblay, RL, Josep Raventos, JD. Ackerman 2015. We show that by using multiple approaches to evaluating population dynamics (traditional and new approaches) we get a more in depth appreciation of the ecology and likely dynamics future patterns of growth of the species.
