Katherine Pulaski

Commander Katherine Pulaski, MD, was chief medical officeraboard the USS Enterprise-D in 2365 while Dr. Beverly Crusher was serving as head of Starfleet Medical.

Service record
Pulaski was part of the rescue team responding to a Tholian attack on a Federation starbase in 2353. There was only one survivor, Kyle Riker, and it was at this time the two met.

Prior to her posting to the Enterprise, Pulaski served as chief medical officer on the USS Repulse under the command of Captain Taggert.

Like her predecessor eighty years before, Dr. Leonard McCoy, Dr. Pulaski had a transporter phobia. She rarely used the transporter while posted to that vessel, preferring to use shuttlecraft whenever possible.

Taggert was fond of Pulaski, and said he would have given her a personal shuttlecraft if she had agreed to remain aboard the Repulse.

USS Enterprise-D
By 2365, when she transferred to the Enterprise, Pulaski carried the rank of commander. Unlike Dr. Crusher, however, she was not considered a bridge officer. Pulaski joined Lieutenant commander Data and Lieutenant La Forge on a holodeck simulation of a Sherlock Holmes mystery. La Forge had unwittingly given the simulated Professor James Moriarty, Holmes's nemesis, sentience by giving the computer the directive to create an adversary which could defeat Data, not Holmes. Moriarty took control of the program and abducted Pulaski. She was held captive but unharmed until Captain Picard was able to convince Moriarty to release control of the holodeck. The Enterprise was sent to investigate the disappearance of the USS Lantreeand discovered that the entire crew had died as a result of premature aging. The Enterprise backtracked the Lantree 's course and ended up at the Darwin Genetic Research Station on Gagarin IV. The scientists on the station, led by Dr. Sara Kingsley, were attempting to genetically engineer several children and accidentally caused their antibodies to become overzealous. The antibodies were designed to seek and destroy harmful organisms before they entered the bodies of the children. The Lantree first officer had been treated for the Thelusian fluprior to visiting Darwin Station, which triggered the immune systems of the children. The antibodies mutated and became airborne, attacking the Lantreecrew as well as the scientists on the station. Dr. Kingsley was adamant that the children could not be carriers of the disease, given their isolation since the infection, plus the fact they have shown no signs. She pleaded with Dr. Pulaski to examine one of the children to rule out the possibility. Pulaski eventually convinced Captain Picard to let her beam one of the youths, encased in styrolite, aboard for examination. She was not content with scans of the child in stasis, and later had Commander Data take her and the teenager onto a shuttlecraft for revival in order to avoid risk to the Enterprise. Unfortunately, the children were indeed the source of the disease, and Pulaski was infected once the youth was removed from the styrolite. She and Data returned to the surface of Gagarin IV, where she worked to find a cure. Fortunately, a cure was devised by Picard and Data, with the help of Commander Riker, La Forge, and Chief O'Brien involving the transporter. Her DNA from before she was infected was obtained from a strand of hair, and it was used to instruct the biofilter on what elements were part of her normal genetic structure. The procedure was perilous; if the disease could not be removed via transporter, Pulaski's pattern would have been dispersed in space to prevent contamination of the Enterprise crew. The procedure was ultimately successful, and used to treat the station staff.

While visiting the Mariposan colony in 2365, Pulaski, along with Commander Riker, was briefly abducted. The Mariposans took epithelial cells from both, intending to use them to preserve their colony which was being affected by replicative fading. Once she and Riker learned of this, they returned to the planet and destroyed the two clones. Dr. Beverly Crusher decided to return to the Enterprise in 2366. Pulaski transferred off the ship sometime prior to Crusher's return.

Medical research
Early in her career, Pulaski authored a groundbreaking research paper called "Linear Models of Viral Propagation". It was still the standard on the subject many years later. She also performed two successful operations involving ocular implants. She offered the procedure to Lieutenant Geordi La Forge in 2365, although he turned down the opportunity.

She had an expertise in heart surgery, and when Picard initially tried to refuse her medical order to proceed to Starbase 515 for a cardiac replacement surgery, she said then that her and her staff would be able to perform the surgery on Enterprise. He refused because of his pride, saying it would be inappropriate for Pulaski to do so. Picard eventually did accompany Wesley Crusher to the starbase (Wesley was going to undergo testing to see if he could continue his Starfleet Academy studies aboard Enterprise), but when complications developed that put his life in jeopardy, the surgeons, who were unqualified to perform risky techniques that might save Picard's life, called for Katherine Pulaski, who was so qualified. When Picard awoke to see Pulaski in the OR, he was annoyed that she was there. When she says she was saving his life, he says that this was a routine operation but Pulaski says Picard is not a commonplace man and despite the fact that the entire crew now knows of what's happened, Pulaski tells Picard that he's still invincible in their eyes.

Dr. Pulaski pioneered a technique used to selectively wipe memory engrams from humanoid species, one that Dr. Beverly Crusher was familiar with.

Romance
Pulaski entered a romantic relationship with Kyle Riker during his convalescence in 2353. She later recalled that she would have married him "in a cold minute", but quickly realized that his priorities were elsewhere and she would not have a stable place in his life. She did not hold this fact against him, though, and they remained amicable. Pulaski never mentioned this to his son Will Riker until Kyle came aboard the Enterprise in 2365 to brief Will on his promotion to captain of the USS Aries, a position Will later turned down. After she and Kyle parted ways, Pulaski had been married and divorced three times. Like with Kyle, she remained good friends with all three men.

Captain Picard
Pulaski and Jean-Luc Picard butted heads over a number of issues during her year aboard the ship. Picard was somewhat offended that her first destination upon boarding the ship was Ten Forward. Pulaski was also upset that the Enterprise was going to do nothing to help the dying civilization on Drema IV. He also argued with her over the surgery needed to replace his cardiac implant. Dr. Pulaski believed she could perform the surgery on the Enterprise, but Picard felt it would be inappropriate and a sign of weakness in front of the crew. She gave him the option of going to Starbase 515, which he did. He nearly died on the operating table from complications, but the Enterprise rushed to the starbase and Pulaski transported down to complete the surgery. Her expertise saved Picard's life. Despite these conflicts, Pulaski had a deep respect for the captain. She admired him for some time prior to her assignment to the Enterprise, and jumped at the chance to transfer when the position became available. Picard did not learn of this until he spoke with Captain Taggert while Pulaski was affected by the virus on Gagarin IV.

Data
Because of her discomfort with technology, Pulaski was not very kind towards Lieutenant Commander Data when she first boarded the ship. She saw him as no more than a machine, pronouncing his name "DAT-ah" rather than "DAY-ta", and did not understand that, as Data pointed out, "One is my name. The other is not." She was also confused when Counselor Troi decided to have Data with her during the delivery of her son, believing that the touch of a Human hand was better than that of an artificial lifeform. She was also condescending towards Data and often spoke to him through other crewmembers. She believed that Data's methodical way of looking at situations meant that he could never solve a traditional Sherlock Holmes mystery, which led to the creation of the program which brought about the sentient Professor Moriarty. Later during the year, however, she began to value Data and look upon him as an equal and as a sentient individual. The major turning point was during the crisis surrounding the Darwin Station children. Data stayed to support Pulaski for a long period of time after she had become infected, something for which she was very grateful. Pulaski even challenged master Zakdorn strategist Sirna Kolrami to a game of Strategema, believing that Data could win. When Data was unsuccessful, he interpreted it as a possible weakness and relieved himself of duty. Dr. Pulaski tried to encourage Data to return to duty, and make him realize that one letdown doesn't necessarily mean total failure, however she was unsuccessful. Finally Captain Picard told Data that a loss can be had with no mistakes made and convinced him to return to duty. Data later forced Kolrami to a stalemate, much to Kolrami's chagrin.

Worf
Pulaski had a certain fascination with Klingon culture. When Lieutenant Worf was diagnosed with the Klingon equivalent of measles, Pulaski vowed that she would tell no one in order to spare Worf's pride. Worf, who later expressed disdain for any kind of doctors due to his Klingon heritage, considered that a friendly gesture on her part, an honorable act that won his friendship. In order to thank her, Worf had her partake in the Klingon tea ceremony. Pulaski had the presence of mind to give herself an antidote for a substance in the tea lethal to Humans. She did not find all parts of Klingon culture particularly appealing, however. She was not very interested in sampling Klingon cuisine. and found the Second Rite of Ascension to be somewhat barbaric. Nevertheless, she honored Worf by her presence, proving her friendship to him. Pulaski was also an accomplished poker player, and joined the Enterprise crew for several poker games. She used to make fun of Worf, because of his icy look during the game
