• Research Interests (300 words)

  I am interested in how plants interact with their biotic (living things, such as pollinators) and abiotic (non-living things, such as landscapes) surroundings. Currently, I’m interested in how wind patterns might affect how the pollen and seeds of different plants move from place to place. To measure if plants move, I isolate DNA from different populations and compare genetic similarities.

  
  
• Profile Question 1

  What is the coolest thing you have discovered or learned about plants?

  
  
• Answer the question you selected for profile question 1 here (300 words):

  One of coolest hypotheses in science is about two of my favorite things: plant dispersal and avocados. In biology, the part of a plant that contains seeds is called a fruit, which includes avocados. Fruits often have mechanisms to help them move around: wind-dispersed fruits usually have a fluffy structure that helps them fly through the air (like dandelions), water-dispersed fruits usually have air pockets that help them float on water (like coconuts), and animal-dispersed fruits are often nutritious and tasty to entice animals into eating and defecating them (like watermelons, peppers, or avocados).
  
  Avocados have been around for much longer than humans have been farming and eating them. However, the avocado seed (the pit) is much too large for humans to eat, even though avocados are nutritious and tasty like other animal-dispersed fruits. Scientists currently hypothesize that avocados evolved to be dispersed by massive, prehistoric animals known as megafauna. In particular, avocados were thought to be dispersed by giant ground sloths, which have since gone extinct, that would eat the fruit whole, move a distance away, and deposit the avocado pit in a new location for it to grow!

  
  
• Profile Question 2

  Do you have advice for students about preparing for a science career?

  
  
• Answer the question you selected for profile question 2 here (300 words):

  Everyone has a different path to science, but here are three pieces of advice that worked for me!
  
  First, being a scientist involves a lot of reading and writing. Track down scientific journal articles that sound interesting to you, even if they feel way over your head. Read the main points in the introduction, walk the methods section step by step, and look at the figures (it takes me a couple hours to read a scientific paper thoroughly!). As you read an article, try to take mental notes on the scientific writing style. Even though scientific articles are sometimes considered “boring”, they often are telling a story about a particular plant or ecosystem that can be pretty exciting!
  
  My second piece of advice is to familiarize yourself with programming. Learning how to program has been one of my best decisions as a scientist because it helps me collect and analyze my data in a whole new, efficient way. Python is a great language to learn for science careers, and there are lots of free tutorials and resources online!
  
  And finally, my last suggestion is to ask questions about the world around you, and then see if you can find the answers, whether through reading the literature or your own experiment! As Dr. Robin Wall Kimmerer—an ecologist at SUNY—said, “I chose botany because I wanted to learn about why [purple] asters and goldenrod looked so beautiful together”. There’s no limit to questions you can ask!

  
  
• Profile Question 3

  What is your favorite plant? Why?

  
  
• Answer the question you selected for profile question 3 here (300 words):

  My favorite plant is Castilleja miniata, commonly known as giant red paintbrush or meadow paintbrush! This plant is native to my home in Oregon and most of the western United States. Meadow paintbrush is my favorite plant for two reasons:
  1) It's a beautiful neon red color (fun fact: the "flowers" of meadow paintbrush are actually modified leaves that pretend to be flowers called bracts!)
  2) It's parasitic; meadow paintbrush roots attach to the roots of other plants and steals nutrients. (It's basically a plant vampire!)

Hi everyone! 

Yay! It's so exciting that you're seeing so much growth!

I hope you have a great time on your trip! :)

It's exciting you're already seeing some growth! Did you only see growth in your smart board treatment? 

Have a great time at your camping trip! :)

Very interesting question! Let's break this down: 

• First, what do plants need to grow? Plants need water molecules to make sugar during photosynthesis. In addition, many plants need certain nutrients to be healthy, which is usually a mix of nitrogen, phosphorus, and potassium. Most plants like very small amounts of these nutrients (1-5%). 
• Second, are these molecules are found in blood? Blood chemistry is going to change depending on the species, but if we look at mammal blood the breakdown is: about 60% is water, <0.5% potassium, about 1% phosphorus, and about 3% nitrogen. So far so good! 
• Finally, are there any molecules in blood that plants don't like? Blood has a whole bunch of molecules in it, including a bunch of complex proteins and fats (about 15% each), which plants can't use. Too many of these molecules might end up making the plants sick. 

So, you might be able to water plants with blood... but the plants would probably be happier just with water! Or very, very diluted blood.
